Debian DSA-2571-1 : libproxy - buffer overflow

critical Nessus Plugin ID 62804

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the libproxy packages.

For the stable distribution (squeeze), this problem has been fixed in version 0.3.1-2+squeeze1.
