Debian Security Advisory DSA-2136-1 security@debian.org

- ------------------------------------------------------------------------
Package : tor
Vulnerability : buffer overflow
Problem type : remote
Debian-specific: no
CVE Id : CVE-2010-1676
Willem Pinckaers discovered that Tor, a tool to enable online anonymity,
does not correctly handle all data read from the network. By supplying
specially crafted packets a remote attacker can cause Tor to overflow its
heap, crashing the process. Arbitrary code execution has not been
confirmed but there is a potential risk.
In the stable distribution (lenny), this update also includes an update of
the IP address for the Tor directory authority gabelmoo and addresses
a weakness in the package's postinst maintainer script.
For the stable distribution (lenny) this problem has been fixed in
version 0.2.1.26-1~lenny+4.
For the testing distribution (squeeze) and the unstable distribution (sid),
this problem has been fixed in version 0.2.1.26-6.
We recommend that you upgrade your tor packages.
Upgrade instructions
- --------------------
If you are using the apt-get package manager, use the line for
sources.list as given below:
apt-get update
will update the internal database
apt-get upgrade
will install corrected packages
You may use an automated update by adding the resources from the
footer to the proper configuration.
