This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11.

An issue present in lowering/register allocation could have led to obscure but deterministic register confusion failures in JITted code that would lead to a potentially exploitable crash. This vulnerability affects Firefox < 91 and Thunderbird < 91.

Mozilla developers reported memory safety bugs present in Firefox 88. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 89.

A type check was missing when handling fonts in PDF.js, which would allow arbitrary JavaScript execution in the PDF.js context. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11.

It was possible to mutate a JavaScript object so that the JIT could crash while tracing it. This vulnerability affects Firefox < 125.

A null pointer dereference may have inadvertently occurred in `pk12util`, and specifically in the `SEC_ASN1DecodeItem_Util` function, when handling malformed or improperly formatted input files. This vulnerability affects Firefox < 133 and Thunderbird < 133.

`NSC_DeriveKey` inadvertently assumed that the `phKey` parameter is always non-NULL. When it was passed as NULL, a segmentation fault (SEGV) occurred, leading to crashes. This behavior conflicted with the PKCS#11 v3.0 specification, which allows `phKey` to be NULL for certain mechanisms. This vulnerability affects Firefox < 133 and Thunderbird < 133.

A Null pointer dereference vulnerability exists in Mozilla Network Security Services due to a missing NULL check in PK11_SignWithSymKey / ssl3_ComputeRecordMACConstantTime, which could let a remote malicious user cause a Denial of Service.

The JavaScript engine did not handle closed generators correctly and it was possible to resume them leading to a nullptr deref. This vulnerability affects Firefox < 141, Firefox ESR < 115.26, Firefox ESR < 128.13, Firefox ESR < 140.1, Thunderbird < 141, Thunderbird < 128.13, and Thunderbird < 140.1.

The session restore helper crashed whenever there was no parameter sent to the message handler. This vulnerability affects Firefox for iOS < 115.

A crash can occur when processing a crafted S/MIME message or an XPI package containing a crafted signature. This can be used as a denial-of-service (DOS) attack because Thunderbird reopens the last seen message on restart, triggering the crash again. This vulnerability affects Thunderbird < 60.5.

In Network Security Services (NSS) before 3.36.7 and before 3.41.1, a malformed signature can cause a crash due to a null dereference, resulting in a Denial of Service.

Null pointer dereference vulnerability in NSS since 3.24.0 was found when server receives empty SSLv2 messages resulting into denial of service by remote attacker.

An issue was discovered in function latm_write_packet in libavformat/latmenc.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts due to a Null pointer dereference.

Insufficient data validation in media in Google Chrome prior to 85.0.4183.121 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

Adobe Flash Player version 32.0.0.433 (and earlier) are affected by an exploitable NULL pointer dereference vulnerability that could result in a crash and arbitrary code execution. Exploitation of this issue requires an attacker to insert malicious strings in an HTTP response that is by default delivered over TLS/SSL.

libavcodec/hevcdec.c in FFmpeg 3.4 and 4.1.2 mishandles detection of duplicate first slices, which allows remote attackers to cause a denial of service (NULL pointer dereference and out-of-array access) or possibly have unspecified other impact via crafted HEVC data.

A vulnerability has been identified in JT2Go (All versions < V13.1.0.2), Teamcenter Visualization (All versions < V13.1.0.2). Affected applications lack proper validation of user-supplied data when parsing ASM files. This could lead to pointer dereferences of a value obtained from untrusted source. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-11899)

An issue was discovered in LibOFX 0.9.14. There is a NULL pointer dereference in the function OFXApplication::startElement in the file lib/ofx_sgml.cpp, as demonstrated by ofxdump.
