Mozilla Firefox CVE-2016-5261 Buffer Overflow Vulnerability
Description
Security researcher Samuel Gro reported an integer overflow error in WebSockets during data buffering on incoming packets when an allocated buffer is resized incorrectly. This results in the buffer array holding the data being shrunk, instead of grown, resulting in attacker controlled data being written at a known offset from the newly allocated buffer. This results in a potentially exploitable crash.
