Debian Security Advisory DSA-2571-1 security@debian.org
http://www.debian.org/security/ Raphael Geissert
November 04, 2012 http://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : libproxy
Vulnerability : buffer overflow
Problem type : remote
Debian-specific: no
CVE ID : CVE-2012-4505
The Red Hat Security Response Team discovered that libproxy, a library
for automatic proxy configuration management, applied insufficient
validation to the Content-Length header sent by a server providing a
proxy.pac file. Such remote server could trigger an integer overflow
and consequently overflow an in-memory buffer.
For the stable distribution (squeeze), this problem has been fixed in
version 0.3.1-2+squeeze1.
For the testing distribution (wheezy), and the unstable distribution
(sid), this problem has been fixed in version 0.3.1-5.1.
We recommend that you upgrade your libproxy packages.
