CVE-2024-11705

State: Published
Severity: 9.1 Critical
Published: Nov 26, 2024
Updated: Nov 27, 2024
Reserved: Nov 25, 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.
