GLSA-200712-17 : exiftags: Multiple vulnerabilities

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200712-17
(exiftags: Multiple vulnerabilities)

Meder Kydyraliev (Google Security) discovered that Exif metadata is not
properly sanitized before being processed, resulting in illegal memory
access in the postprop() and other functions (CVE-2007-6354). He also
discovered integer overflow vulnerabilities in the parsetag() and other
functions (CVE-2007-6355) and an infinite recursion in the readifds()
function caused by recursive IFD references (CVE-2007-6356).

Impact :

An attacker could entice the user of an application making use of
exiftags or an application included in exiftags to load an image file
with specially crafted Exif tags, possibly resulting in the execution
of arbitrary code with the privileges of the user running the
application or a Denial of Service.

Workaround :

There is no known workaround at this time.

Solution :

All exiftags users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-gfx/exiftags-1.01'

Risk factor :

Critical / CVSS Base Score : 10.0
