The remote attackers can then exploit the vulnerability to launch a denial-of-service (DoS) attack. We have already fixed the vulnerability in the following versions: QTS 5.2.7.3297 build 20251024 and later QuTS hero h5.2.7.3297 build 20251024 and later QuTS hero h5.3.1.3292 build 20251024 and later

The QCMAP_Web_CLIENT binary in the Qualcomm QCMAP software suite prior to versions released in October 2020 does not validate the return value of a strstr() or strchr() call in the Tokenizer() function. An attacker who invokes the web interface with a crafted URL can crash the process, causing denial of service. This version of QCMAP is used in many kinds of networking devices, primarily mobile hotspots and LTE routers.

In teler before version 0.0.1, if you run teler inside a Docker container and encounter `errors.Exit` function, it will cause denial-of-service (`SIGSEGV`) because it doesn't get process ID and process group ID of teler properly to kills. The issue is patched in teler 0.0.1 and 0.0.1-dev5.1.

The JWT library in NATS nats-server before 2.1.9 allows a denial of service (a nil dereference in Go code).

In Wireshark 3.2.0 to 3.2.6 and 3.0.0 to 3.0.13, the BLIP protocol dissector has a NULL pointer dereference because a buffer was sized for compressed (not uncompressed) messages. This was addressed in epan/dissectors/packet-blip.c by allowing reasonable compression ratios and rejecting ZIP bombs.

In the Lustre file system before 2.12.3, mdt_object_remote in the mdt module has a NULL pointer dereference and panic due to the lack of validation for specific fields of packets sent by a client.

A denial-of-service vulnerability exists in the omec-project UPF (pfcpiface component) in version upf-epc-pfcpiface:2.1.3-dev. When the UPF receives a PFCP Session Report Response that is missing the mandatory Cause Information Element, the session report handler dereferences a nil pointer instead of rejecting the malformed message. This triggers a panic and terminates the UPF process. An attacker who can send PFCP Session Report Response messages to the UPF's N4/PFCP endpoint can exploit this flaw to repeatedly crash the UPF and disrupt user-plane services.

Wazuh is a free and open source platform used for threat prevention, detection, and response. fillData() implementation does not check whether value is NULL or not before calling os_strdup() on it. A compromised agent can cause a crash of analysisd by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can cause analysisd to crash and make it unavailable. This vulnerability is fixed in 4.10.2.

exprListAppendList in window.c in SQLite 3.30.1 allows attackers to trigger an invalid pointer dereference because constant integer values in ORDER BY clauses of window definitions are mishandled.

A vulnerability in the web server of Cisco Integrated Management Controller (IMC) could allow an unauthenticated, remote attacker to cause the web server process to crash, causing a denial of service (DoS) condition on an affected system. The vulnerability is due to insufficient validation of user-supplied input on the web interface. An attacker could exploit this vulnerability by submitting a crafted HTTP request to certain endpoints of the affected software. A successful exploit could allow an attacker to cause the web server to crash. Physical access to the device may be required for a restart.

An issue was discovered in the Linux kernel 4.4.x before 4.4.195. There is a NULL pointer dereference in rds_tcp_kill_sock() in net/rds/tcp.c that will cause denial of service, aka CID-91573ae4aed0.

An issue was discovered in tls_verify_crl in ProFTPD before 1.3.6. Direct dereference of a NULL pointer (a variable initialized to NULL) leads to a crash when validating the certificate of a client connecting to the server in a TLS client/server mutual-authentication setup.

An issue was discovered in res_pjsip_t38.c in Sangoma Asterisk through 13.x and Certified Asterisk through 13.21-x.

A Null Pointer Dereference issue was discovered in Schneider Electric Wonderware ArchestrA Logger, versions 2017.426.2307.1 and prior. The null pointer dereference vulnerability could allow an attacker to crash the logger process, causing a denial of service for logging and log-viewing (applications that use the Wonderware ArchestrA Logger continue to run when the Wonderware ArchestrA Logger service is unavailable).

DjVuLibre 3.5.27 has a NULL pointer dereference in the function DJVU::filter_fv at IW44EncodeCodec.cpp.

An issue was discovered in Envoy 1.12.0. Upon receipt of a malformed HTTP request without a Host header, it sends an internally generated "Invalid request" response. This internally generated response is dispatched through the configured encoder filter chain before being sent to the client. An encoder filter that invokes route manager APIs that access a request's Host header causes a NULL pointer dereference, resulting in abnormal termination of the Envoy process.

RIOT 2019.07 contains a NULL pointer dereference in the MQTT-SN implementation (asymcute), potentially allowing an attacker to crash a network node running RIOT. This requires spoofing an MQTT server response. To do so, the attacker needs to know the MQTT MsgID of a pending MQTT protocol message and the ephemeral port used by RIOT's MQTT implementation. Additionally, the server IP address is required for spoofing the packet.

Hydra through 0.1.8 has a NULL pointer dereference and daemon crash when processing POST requests that lack a Content-Length header. read.c, request.c, and util.c contribute to this. The process_header_end() function calls boa_atoi(), which ultimately calls atoi() on a NULL pointer.

Wazuh is a free and open source platform used for threat prevention, detection, and response. Prior to 4.11.0, fim_alert() implementation does not check whether the return value of ctime_r is NULL or not before calling strdup() on it. A compromised agent can cause a crash of analysisd by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can cause analysisd to crash and make it unavailable. This vulnerability is fixed in 4.11.0.

A NULL pointer dereference in Draytek devices Vigor 165/166 prior to v4.2.6 , Vigor 2620/LTE200 prior to v3.9.8.8, Vigor 2860/2925 prior to v3.9.7, Vigor 2862/2926 prior to v3.9.9.4, Vigor 2133/2762/2832 prior to v3.9.8, Vigor 2135/2765/2766 prior to v4.4.5.1, Vigor 2865/2866/2927 prior to v4.4.5.3, Vigor 2962/3910 prior to v4.3.2.7, Vigor 3912 prior to v4.3.5.2, and Vigor 2925 up to v3.9.6 allows attackers to cause a Denial of Service (DoS) via a crafted DHCP request.

7-Zip is a file archiver with a high compression ratio. 7-Zip supports extracting from Compound Documents. Prior to version 25.0.0, a null pointer dereference in the Compound handler may lead to denial of service. Version 25.0.0 contains a fix cor the issue.

Onigmo through 6.2.0 has a NULL pointer dereference in onig_error_code_to_str because of fetch_token in regparse.c.

Helm is a tool for managing Charts, pre-configured Kubernetes resources. Versions prior to 3.10.3 are subject to NULL Pointer Dereference in the_chartutil_ package that can cause a segmentation violation. The _chartutil_ package contains a parser that loads a JSON Schema validation file. For example, the Helm client when rendering a chart will validate its values with the schema file. The _chartutil_ package parses the schema file and loads it into structures Go can work with. Some schema files can cause array data structures to be created causing a memory violation. Applications that use the _chartutil_ package in the Helm SDK to parse a schema file can suffer a Denial of Service when that input causes a panic that cannot be recovered from. Helm is not a long running service so the panic will not affect future uses of the Helm client. This issue has been patched in 3.10.3. SDK users can validate schema files that are correctly formatted before passing them to the _chartutil_ functions.
