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.
