CVE-2024-11705

Mozilla Firefox NULL pointer dereference

9.1 CRITICALEPSS 0.66%
  1. Published26 Nov 2024

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.
