Use-after-free vulnerability in TLS 1.2 exchanges in Mozilla Firefox, Firefox ESR and Thunderbird via generating handshake hashes (Mac OS X)ID: oval:org.secpod.oval:def:42279 | Date: (C)2017-10-10 (M)2023-11-19 |
Class: VULNERABILITY | Family: macos |
Mozilla Firefox before 56.0, Firefox ESR before 52.4 or Thunderbird 52.4 :- During TLS 1.2 exchanges, handshake hashes are generated which point to a message buffer. This saved data is used for later messages but in some cases, the handshake transcript can exceed the space available in the current buffer, causing the allocation of a new buffer. This leaves a pointer pointing to the old, freed buffer, resulting in a use-after-free when handshake hashes are then calculated afterwards. This can result in a potentially exploitable crash.
