A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to 4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will be lost.

Integer overflow in io-ico.c in gdk-pixbuf allows context-dependent attackers to cause a denial of service (segmentation fault and application crash) via a crafted image entry offset in an ICO file, which triggers an out-of-bounds read, related to compiler optimizations.

A vulnerability was found in Undertow where the ProxyProtocolReadListener reuses the same StringBuilder instance across multiple requests. This issue occurs when the parseProxyProtocolV1 method processes multiple requests on the same HTTP connection. As a result, different requests may share the same StringBuilder instance, potentially leading to information leakage between requests or responses. In some cases, a value from a previous request or response may be erroneously reused, which could lead to unintended data exposure. This issue primarily results in errors and connection termination but creates a risk of data leakage in multi-request environments.

The make_available_at_least function in io-tiff.c in gdk-pixbuf allows context-dependent attackers to cause a denial of service (infinite loop) via a large TIFF file.

gdk-pixbuf-thumbnailer.c in gdk-pixbuf allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors related to printing an error message.

A flaw was found in the Poppler's Pdfinfo utility. This issue occurs when using -dests parameter with pdfinfo utility. By using certain malformed input files, an attacker could cause the utility to crash, leading to a denial of service.

A denial of service flaw was found in the way BIND handled DNSSEC validation. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response.

A null pointer dereference flaw was found in Libtiff via `tif_dirinfo.c`. This issue may allow an attacker to trigger memory allocation failures through certain means, such as restricting the heap space size or injecting faults, causing a segmentation fault. This can cause an application crash, eventually leading to a denial of service.

GNOME libsoup before 3.6.1 has an infinite loop, and memory consumption. during the reading of certain patterns of WebSocket data from clients.

A flaw was found in Bombastic, which allows authenticated users to upload compressed (bzip2 or zstd) SBOMs. The API endpoint verifies the presence of some fields and values in the JSON. To perform this verification, the uploaded file must first be decompressed.

A flaw was found in all ipa versions 4.x.x through 4.8.0. When sending a very long password (>= 1,000,000 characters) to the server, the password hashing process could exhaust memory and CPU leading to a denial of service and the website becoming unresponsive. The highest threat from this vulnerability is to system availability.

A flaw was found in Podman. This issue may allow an attacker to create a specially crafted container that, when configured to share the same IPC with at least one other container, can create a large number of IPC resources in /dev/shm. The malicious container will continue to exhaust resources until it is out-of-memory (OOM) killed. While the malicious container's cgroup will be removed, the IPC resources it created are not. Those resources are tied to the IPC namespace that will not be removed until all containers using it are stopped, and one non-malicious container is holding the namespace open. The malicious container is restarted, either automatically or by attacker control, repeating the process and increasing the amount of memory consumed. With a container configured to restart always, such as `podman run --restart=always`, this can result in a memory-based denial of service of the system.

libgedit.a in GNOME gedit through 3.22.1 allows remote attackers to cause a denial of service (CPU consumption) via a file that begins with many '\0' characters.

No Limit on Number of Open Sessions / Bad Session Close Behaviour in dnf5daemon-server before 5.1.17 allows a malicious user to impact Availability via No Limit on Number of Open Sessions. There is no limit on how many sessions D-Bus clients may create using the `open_session()` D-Bus method. For each session a thread is created in dnf5daemon-server. This spends a couple of hundred megabytes of memory in the process. Further connections will become impossible, likely because no more threads can be spawned by the D-Bus service.

An incomplete fix for ose-olm-catalogd-container was issued for the Rapid Reset Vulnerability (CVE-2023-39325/CVE-2023-44487) where only unauthenticated streams were protected, not streams created by authenticated sources.

A vulnerability was found in JWCrypto. This flaw allows an attacker to cause a denial of service (DoS) attack and possible password brute-force and dictionary attacks to be more resource-intensive. This issue can result in a large amount of computational consumption, causing a denial of service attack.

A flaw was discovered in Wildfly's EJB Client as shipped with Red Hat JBoss EAP 7, where some specific EJB transaction objects may get accumulated over the time and can cause services to slow down and eventaully unavailable. An attacker can take advantage and cause denial of service attack and make services unavailable.

An out-of-memory flaw was found in libtiff. Passing a crafted tiff file to TIFFOpen() API may allow a remote attacker to cause a denial of service via a craft input with size smaller than 379 KB.

A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.

A flaw was found in IPA, all 4.6.x versions before 4.6.7, all 4.7.x versions before 4.7.4 and all 4.8.x versions before 4.8.3, in the way the internal function ber_scanf() was used in some components of the IPA server, which parsed kerberos key data. An unauthenticated attacker who could trigger parsing of the krb principal key could cause the IPA server to crash or in some conditions, cause arbitrary code to be executed on the server hosting the IPA server.

A use-after-free flaw was found in btrfs_get_dev_args_from_path in fs/btrfs/volumes.c in btrfs file-system in the Linux Kernel. This flaw allows a local attacker with special privileges to cause a system crash or leak internal kernel information

A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the "rpcecho" service operates with only one worker in the main RPC task, allowing calls to the "rpcecho" server to be blocked for a specified time, causing service disruptions. This disruption is triggered by a "sleep()" call in the "dcesrv_echo_TestSleep()" function under specific conditions. Authenticated users or attackers can exploit this vulnerability to make calls to the "rpcecho" server, requesting it to block for a specified duration, effectively disrupting most services and leading to a complete denial of service on the AD DC. The DoS affects all other services as "rpcecho" runs in the main RPC task.

A flaw was found in Samba. It is susceptible to a vulnerability where multiple incompatible RPC listeners can be initiated, causing disruptions in the AD DC service. When Samba's RPC server experiences a high load or unresponsiveness, servers intended for non-AD DC purposes (for example, NT4-emulation "classic DCs") can erroneously start and compete for the same unix domain sockets. This issue leads to partial query responses from the AD DC, causing issues such as "The procedure number is out of range" when using tools like Active Directory Users. This flaw allows an attacker to disrupt AD DC services.

A flaw was found in gnome-remote-desktop. Once gnome-remote-desktop listens for RDP connections, an unauthenticated attacker can exhaust system resources and repeatedly crash the process. There may be a resource leak after many attacks, which will also result in gnome-remote-desktop no longer being able to open files even after it is restarted via systemd.

A flaw was found in OpenJPEG. A resource exhaustion can occur in the opj_t1_decode_cblks function in tcd.c through a crafted image file, causing a denial of service.

A flaw was found in OpenJPEG. Maliciously constructed pictures can cause the program to enter a large loop and continuously print warning messages on the terminal.

In xml.rs in GNOME librsvg before 2.46.2, a crafted SVG file with nested patterns can cause denial of service when passed to the library for processing. The attacker constructs pattern elements so that the number of final rendered objects grows exponentially.

A Developer persona can bring down the Authorino service, preventing the evaluation of all AuthPolicies on the cluster

The Authorino service in the Red Hat Connectivity Link is the authorization service for zero trust API security. Authorino allows the users with developer persona to add callbacks to be executed to HTTP endpoints once the authorization process is completed. It was found that an attacker with developer persona access can add a large number of those callbacks to be executed by Authorino and as the authentication policy is enforced by a single instance of the service, this leada to a Denial of Service in Authorino while processing the post-authorization callbacks.

An uncontrolled resource consumption flaw was found in openstack-neutron. This flaw allows a remote authenticated user to query a list of security groups for an invalid project. This issue creates resources that are unconstrained by the user's quota. If a malicious user were to submit a significant number of requests, this could lead to a denial of service.

A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system.

A flaw was found in the subsequent get_user_pages_fast in the Linux kernel’s interface for symmetric key cipher algorithms in the skcipher_recvmsg of crypto/algif_skcipher.c function. This flaw allows a local user to crash the system.

A vulnerability was found in the ilab model serve component, where improper handling of the best_of parameter in the vllm JSON web API can lead to a Denial of Service (DoS). The API used for LLM-based sentence or chat completion accepts a best_of parameter to return the best completion from several options. When this parameter is set to a large value, the API does not handle timeouts or resource exhaustion properly, allowing an attacker to cause a DoS by consuming excessive system resources. This leads to the API becoming unresponsive, preventing legitimate users from accessing the service.

A flaw was found in Open Virtual Network where the service monitor MAC does not properly rate limit. This issue could allow an attacker to cause a denial of service, including on deployments with CoPP enabled and properly configured.

A flaw was found in the cockpit package. This flaw allows an authenticated user to kill any process when enabling the pam_env's user_readenv option, which leads to a denial of service (DoS) attack.

A flaw was found in the QEMU disk image utility (qemu-img) 'info' command. A specially crafted image file containing a `json:{}` value describing block devices in QMP could cause the qemu-img process on the host to consume large amounts of memory or CPU time, leading to denial of service or read/write to an existing external file.

It was found that URLResource.getLastModified() in Undertow closes the file descriptors only when they are finalized which can cause file descriptors to exhaust. This leads to a file handler leak.

It was discovered that fsync(2) system call in glusterfs client code leaks memory. An authenticated attacker could use this flaw to launch a denial of service attack by making gluster clients consume memory of the host machine.

A flaw was found in the 389 Directory Server that allows users to cause a crash in the LDAP server using ldapsearch with server side sort.

A flaw was found in NetworkManager. When a system running NetworkManager with DEBUG logs enabled and an interface eth1 configured with LLDP enabled, a malicious user could inject a malformed LLDP packet. NetworkManager would crash, leading to a denial of service.

go-libp2p is the offical libp2p implementation in the Go programming language. Version `0.18.0` and older of go-libp2p are vulnerable to targeted resource exhaustion attacks. These attacks target libp2p’s connection, stream, peer, and memory management. An attacker can cause the allocation of large amounts of memory, ultimately leading to the process getting killed by the host’s operating system. While a connection manager tasked with keeping the number of connections within manageable limits has been part of go-libp2p, this component was designed to handle the regular churn of peers, not a targeted resource exhaustion attack. Users are advised to upgrade their version of go-libp2p to version `0.18.1` or newer. Users unable to upgrade may consult the denial of service (dos) mitigation page for more information on how to incorporate mitigation strategies, monitor your application, and respond to attacks.

Jerryscript commit 1a2c047 was discovered to contain a segmentation violation via the component build/bin/jerry.

An issue was discovered in ONOS 2.5.1. The purge-requested intent remains on the list, but it does not respond to changes in topology (e.g., link failure). In combination with other applications, it could lead to a failure of network management.

An Uncontrolled Resource Consumption vulnerability in the H.323 ALG (Application Layer Gateway) of  Juniper Networks Junos OS on SRX Series and MX Series with SPC3 and MS-MPC/MIC, allows an unauthenticated network-based attacker to send specific packets causing traffic loss leading to Denial of Service (DoS).  Continued receipt and processing of these specific packets will sustain the Denial of Service condition. The memory usage can be monitored using the below command.   user@host> show usp memory segment sha data objcache jsf  This issue affects SRX Series and MX Series with SPC3 and MS-MPC/MIC:  *  20.4 before 20.4R3-S10,  *  21.2 before 21.2R3-S6,  *  21.3 before 21.3R3-S5,  *  21.4 before 21.4R3-S6,  *  22.1 before 22.1R3-S4,  *  22.2 before 22.2R3-S2,  *  22.3 before 22.3R3-S1,  *  22.4 before 22.4R3,  *  23.2 before 23.2R2.

The ethernet-lldp component in Cisco IOS 12.2 before 12.2(33)SXJ1 does not properly support a large number of LLDP Management Address (MA) TLVs, which allows remote attackers to cause a denial of service (device crash) via crafted LLDPDUs, aka Bug ID CSCtj22354.

Traefik (pronounced traffic) is a modern HTTP reverse proxy and load balancer for deploying microservices. There is a vulnerability in Go when parsing the HTTP headers, which impacts Traefik. HTTP header parsing could allocate substantially more memory than required to hold the parsed headers. This behavior could be exploited to cause a denial of service. This issue has been patched in versions 2.9.10 and 2.10.0-rc2.
