Date Reported:
04 Nov 2012
Affected Packages:
libproxy
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CVE-2012-4505.
More information:

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.
