sol95698826: LZO vulnerability CVE-2014-4607
Security Advisory
Original Publication Date: 02/03/2016
Vulnerability Description
An integer overflow flaw was found in the way the lzo library decompressed
certain archives compressed with the LZO algorithm. An attacker could create a
specially crafted LZO-compressed input that, when decompressed by an
application using the lzo library, would cause that application to crash or,
potentially, execute arbitrary code. (CVE-2014-4607 - reserved)
Impact
An attacker may be able to cause an application to crash or potentially
execute arbitrary code when exploited.
