CVE-2017-7805 (GCVE-0-2017-7805)

Vulnerability from cvelistv5 – Published: 2018-06-11 21:00 – Updated: 2024-08-05 16:12
VLAI?
Summary
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. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4.
Severity ?
No CVSS data available.
