Debian Security Advisory DSA-3741-1 security@debian.org

December 20, 2016 https://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : tor
CVE ID : CVE-2016-1254
Debian Bug : 848847
It was discovered that Tor, a connection-based low-latency anonymous
communication system, may read one byte past a buffer when parsing
hidden service descriptors. This issue may enable a hostile hidden
service to crash Tor clients depending on hardening options and malloc
implementation.
For the stable distribution (jessie), this problem has been fixed in
version 0.2.5.12-4.
For the testing (stretch) and unstable (sid) distributions, this
problem has been fixed in version 0.2.9.8-2.
We recommend that you upgrade your tor packages.
