Qt is a cross-platform GUI toolkit used by KDE.
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.
All Qt users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/qt-3.3.4-r8"
OS | Version | Architecture | Package | Version | Filename |
---|---|---|---|---|---|
