GLSA-200509-18 : Qt: Buffer overflow in the included zlib library

High Nessus Plugin ID 19817

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200509-18 (Qt: Buffer overflow in the included zlib library)

Qt links to a bundled vulnerable version of zlib when emerged with the zlib USE-flag disabled. This may lead to a buffer overflow.
Impact :

By creating a specially crafted compressed data stream, attackers can overwrite data structures for applications that use Qt, resulting in a Denial of Service or potentially arbitrary code execution.
Workaround :

Emerge Qt with the zlib USE-flag enabled.

Solution

All Qt users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=x11-libs/qt-3.3.4-r8'
