CVE-2024-11705

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-11705
`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.

Summary
  • (es) `NSC_DeriveKey` supuso inadvertidamente que el parámetro `phKey` siempre es distinto de NULL. Cuando se pasaba como NULL, se producía un error de segmentación (SEGV), lo que provocaba bloqueos. Este comportamiento entraba en conflicto con la especificación PKCS#11 v3.0, que permite que `phKey` sea NULL para ciertos mecanismos. Esta vulnerabilidad afecta a Firefox &lt; 133 y Thunderbird &lt; 133.
