CVE-2024-11705

CRITICAL

Thunderbird < 133.0 - Denial of Service via NULL Pointer Dereference in NSC_DeriveKey

Title source: llm
STIX 2.1

Description

`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.
