[GLSA-200509-18] Qt: Buffer overflow in the included zlib library Vulnerability Scan
Vulnerability Scan Summary
Qt: Buffer overflow in the included zlib library
Detailed Explanation for this Vulnerability Test
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.
