New socat packages are available for Debian GNU/Linux to fix a arbitrary code execution



[SECURITY] [DSA 2090-1] New socat packages fix arbitrary code execution

Package : socat
Vulnerability : incorrect user-input validation
Problem type : remote
Debian-specific: no
Debian bug : 591443
CVE ID : CVE-2010-2799

A stack overflow vulnerability was found in socat that allows an
attacker to execute arbitrary code with the privileges of the socat
process.

This vulnerability can only be exploited when an attacker is able to
inject more than 512 bytes of data into socat's argument.

A vulnerable scenario would be a CGI script that reads data from
clients and uses (parts of) this data as argument for a socat
invocation.

For the stable distribution (lenny), this problem has been fixed in
version 1.6.0.1-1+lenny1.

For the unstable distribution (sid), this problem has been fixed in
version 1.7.1.3-1.

We recommend that you upgrade your socat package.
