Debian DSA-145-1 : tinyproxy - doubly freed memory

high Nessus Plugin ID 14982

Synopsis

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

Description

The authors of tinyproxy, a lightweight HTTP proxy, discovered a bug in the handling of some invalid proxy requests. Under some circumstances, an invalid request may result in allocated memory being freed twice. This can potentially result in the execution of arbitrary code.

Solution

Upgrade the tinyproxy package immediately.

This problem has been fixed in version 1.4.3-2woody2 for the current stable distribution (woody) and in version 1.4.3-3 for the unstable distribution (sid). The old stable distribution (potato) is not affected by this problem.
