NUL Termination Vulnerability in Tor Versions 0.2.8.9 and 0.2.9.x

CVE-2016-8860 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

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.
