December 2, 2011 - ProxyAV buffer overflow in libpng (CVE-2010-1205)
High, CVSS v2 base score: 7.8 (AV:N/AC:L/Au:N/C:P/I:P/A:P)
ProxyAV uses a version of libpng that is vulnerable to a buffer overflow attack. This vulnerability could allow a remote attacker to read and modify ProxyAV data.
All versions of ProxyAV prior to 188.8.131.52 are vulnerable.
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 184.108.40.206 contains an upgrade to libpng version 1.2.46 fixing this CVE.
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.
