CVE-2016-8860

HIGH

Tor <0.2.8.9 and 0.2.9.x <0.2.9.4-alpha - DoS

Title source: llm
STIX 2.1

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.
