ISSUES

CVE-2010-1205 - CVSS v2 base score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)

ProxyAV uses libpng version 1.2.8 to generate statistical graphs in PNG format.  This version of libpng is vulnerable to a buffer overflow attack.  It is possible that a remote attacker could execute arbitrary code on ProxyAV through this library that would run with escalated privileges.

ProxyAV 3.4.1.1 contains an upgrade to libpng version 1.2.46 fixing this CVE.

MITIGATION

Deploying ProxyAV behind a firewall and adding constraints on what IP addresses can be used to connect to ProxyAV will greatly limit the ability to attack a ProxyAV installation.
