Synopsis

========

 

Multiple vulnerabilities have been found in libexif and exif, some of

which may allow execution of arbitrary code.

 

Background

==========

 

libexif is a library for parsing, editing and saving Exif metadata from

images. exif is a small command line interface for libexif.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

2 affected packages

 

Description

===========

 

Multiple vulnerabilities have been discovered in libexif and exif.

Please review the CVE identifiers referenced below for details.

 

Impact

======

 

A remote attacker could entice a user to open a specially crafted image

file using exif or an application linked against libexif, possibly

resulting in execution of arbitrary code with the privileges of the

process or a Denial of Service condition.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All libexif users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=media-libs/libexif-0.6.21"

 

Packages which depend on this library may need to be recompiled. Tools

such as revdep-rebuild may assist in identifying some of these

packages.

 

All exif users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=media-gfx/exif-0.6.21"
