A flaw was found in OpenEXR's B44 uncompression functionality in versions before 3.0.0-beta. An attacker who is able to submit a crafted file to OpenEXR could trigger shift overflows, potentially affecting application availability.

In Apache SpamAssassin before 3.4.3, a message can be crafted in a way to use excessive resources. Upgrading to SA 3.4.3 as soon as possible is the recommended fix but details will not be shared publicly.

A regular expression based DoS vulnerability in Action Dispatch <6.1.7.1 and <7.0.4.1 related to the If-None-Match header. A specially crafted HTTP If-None-Match header can cause the regular expression engine to enter a state of catastrophic backtracking, when on a version of Ruby below 3.2.0. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability All users running an affected release should either upgrade or use one of the workarounds immediately.

In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the GSS-API dissector could crash. This was addressed in epan/dissectors/packet-gssapi.c by ensuring that a valid dissector is called.

In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the DOF dissector could crash. This was addressed in epan/dissectors/packet-dof.c by properly handling generated IID and OID bytes.

In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the SRVLOC dissector could crash. This was addressed in epan/dissectors/packet-srvloc.c by preventing a heap-based buffer under-read.

In Eclipse OpenJ9 prior to the 0.14.0 release, the Java bytecode verifier incorrectly allows a method to execute past the end of bytecode array causing crashes. Eclipse OpenJ9 v0.14.0 correctly detects this case and rejects the attempted class load.

In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the NetScaler file parser could crash. This was addressed in wiretap/netscaler.c by improving data validation.

Mozilla Firefox 3.5.2 on Windows XP, in some situations possibly involving an incompletely configured protocol handler, does not properly implement setting the document.location property to a value specifying a protocol associated with an external application, which allows remote attackers to cause a denial of service (memory consumption) via vectors involving a series of function calls that set this property, as demonstrated by (1) the chromehtml: protocol and (2) the aim: protocol.

Redis is an open source, in-memory database that persists on disk. When parsing an incoming Redis Standard Protocol (RESP) request, Redis allocates memory according to user-specified values which determine the number of elements (in the multi-bulk header) and size of each element (in the bulk header). An attacker delivering specially crafted requests over multiple connections can cause the server to allocate significant amount of memory. Because the same parsing mechanism is used to handle authentication requests, this vulnerability can also be exploited by unauthenticated users. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. An additional workaround to mitigate this problem without patching the redis-server executable is to block access to prevent unauthenticated users from connecting to Redis. This can be done in different ways: Using network access control tools like firewalls, iptables, security groups, etc. or Enabling TLS and requiring users to authenticate using client side certificates.

An issue was discovered in klibc before 2.0.9. An integer overflow in the cpio command may result in a NULL pointer dereference on 64-bit systems.

mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. When mod_auth_openidc versions prior to 2.4.9 are configured to use an unencrypted Redis cache (`OIDCCacheEncrypt off`, `OIDCSessionType server-cache`, `OIDCCacheType redis`), `mod_auth_openidc` wrongly performed argument interpolation before passing Redis requests to `hiredis`, which would perform it again and lead to an uncontrolled format string bug. Initial assessment shows that this bug does not appear to allow gaining arbitrary code execution, but can reliably provoke a denial of service by repeatedly crashing the Apache workers. This bug has been corrected in version 2.4.9 by performing argument interpolation only once, using the `hiredis` API. As a workaround, this vulnerability can be mitigated by setting `OIDCCacheEncrypt` to `on`, as cache keys are cryptographically hashed before use when this option is enabled.

agent/snmp_agent.c in snmpd in net-snmp 5.0.9 in Red Hat Enterprise Linux (RHEL) 3 allows remote attackers to cause a denial of service (daemon crash) via a crafted SNMP GETBULK request that triggers a divide-by-zero error. NOTE: this vulnerability exists because of an incorrect fix for CVE-2008-4309.

The JavaScript engine in Mozilla Firefox before 3.0.9, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.16 allows remote attackers to cause a denial of service (application crash) and possibly trigger memory corruption via vectors involving JSOP_DEFVAR and properties that lack the JSPROP_PERMANENT attribute.

A certain Debian patch for OpenSSH before 4.3p2-9etch3 on etch; before 4.6p1-1 on sid and lenny; and on other distributions such as SUSE uses functions that are not async-signal-safe in the signal handler for login timeouts, which allows remote attackers to cause a denial of service (connection slot exhaustion) via multiple login attempts. NOTE: this issue exists because of an incorrect fix for CVE-2006-5051.

hostapd before 2.6, in EAP mode, makes calls to the rand() and random() standard library functions without any preceding srand() or srandom() call, which results in inappropriate use of deterministic values. This was fixed in conjunction with CVE-2016-10743.

The JavaScript engine in Mozilla Firefox 3.x before 3.0.9, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.16 allows remote attackers to cause a denial of service (application crash) and possibly trigger memory corruption via vectors involving (1) js_FindPropertyHelper, related to the definitions of Math and Date; and (2) js_CheckRedeclaration.

Mozilla Firefox 2.0.0.20 and earlier allows remote attackers to cause a denial of service (application crash) via nested calls to the window.print function, as demonstrated by a window.print(window.print()) in the onclick attribute of an INPUT element.

Mozilla Firefox 3.0.1 and earlier allows remote attackers to cause a denial of service (browser hang) by calling the window.print function in a loop, aka a "printing DoS attack," possibly a related issue to CVE-2009-0821.

It was found that the fix for CVE-2018-14648 in 389-ds-base, versions 1.4.0.x before 1.4.0.17, was incorrectly applied in RHEL 7.5. An attacker would still be able to provoke excessive CPU consumption leading to a denial of service.

Puma is a concurrent HTTP 1.1 server for Ruby/Rack applications. The fix for CVE-2019-16770 was incomplete. The original fix only protected existing connections that had already been accepted from having their requests starved by greedy persistent-connections saturating all threads in the same process. However, new connections may still be starved by greedy persistent-connections saturating all threads in all processes in the cluster. A `puma` server which received more concurrent `keep-alive` connections than the server had threads in its threadpool would service only a subset of connections, denying service to the unserved connections. This problem has been fixed in `puma` 4.3.8 and 5.3.1. Setting `queue_requests false` also fixes the issue. This is not advised when using `puma` without a reverse proxy, such as `nginx` or `apache`, because you will open yourself to slow client attacks (e.g. slowloris). The fix is very small and a git patch is available for those using unsupported versions of Puma.

ircII before 20210314 allows remote attackers to cause a denial of service (segmentation fault and client crash, disconnecting the victim from an IRC server) via a crafted CTCP UTC message.
