Description Andrej Nemec 2017-01-11 15:40:06 UTC

An integer overflow vulnerability was found in icoutils in the wrestool program. A maliciously crafted file could make the application crash or possibly allow code execution. This is a CVE for an insufficient patch for CVE-2017-5208.

Comment 1 Andrej Nemec 2017-01-11 15:42:13 UTC

Statement:

This issue did not affect the versions of icoutils as shipped with Red Hat
Enterprise Linux 7 as they did not backport the vulnerable patches
provided to fix a previous flaw (CVE-2017-5208).
