Package : tor
Version : 0.2.4.27-3
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 Debian 7 "Wheezy", these problems have been fixed in version
0.2.4.27-3.
We recommend that you upgrade your tor packages.
