CWE-119

Description

Tor before 0.2.8.9 and 0.2.9.x before 0.2.9.4-alpha had internal functions that were entitled to expect that buf_t data had NUL termination, but the implementation of or/buffers.c did not ensure that NUL termination was present, which allows remote attackers to cause a denial of service (client, hidden service, relay, or authority crash) via crafted data.

Affected configurations

• torproject tor (<= 0.2.8.8) • torproject tor 0.2.9.0 • torproject tor 0.2.9.1 • torproject tor 0.2.9.2 • torproject tor 0.2.9.3
