Description

The remote host is affected by the vulnerability described in GLSA-200603-18 (Pngcrush: Buffer overflow)

Carsten Lohrke of Gentoo Linux reported that Pngcrush contains a
vulnerable version of zlib (GLSA 200507-19).

Impact :

By creating a specially crafted data stream, attackers can
overwrite data structures for applications that use Pngcrush, resulting
in a Denial of Service and potentially arbitrary code execution.

Workaround :

There is no known workaround at this time.
