GLSA-200509-18 : Qt: Buffer overflow in the included zlib library
High Nessus Plugin ID 19817
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
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.
Emerge Qt with the zlib USE-flag enabled.
SolutionAll Qt users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=x11-libs/qt-3.3.4-r8'
