Gentoo Linux Security Advisory

Title: libexif: Multiple vulnerabilities (GLSA 200712-15)
Severity: normal
Exploitable: remote
Date: December 29, 2007
Bug(s): #202350
ID: 200712-15

Synopsis

Two vulnerabilities in libexif possibly allow for the execution of arbitrary code or a Denial of Service.

Background

libexif is a library for parsing, editing and saving Exif metadata from images. Exif, the Exchangeable image file format, specifies the addition of metadata tags to JPEG, TIFF and RIFF files.

Affected Packages

Package: media-libs/libexif
Vulnerable: < 0.6.16-r1
Unaffected: >= 0.6.16-r1
Architectures: All supported architectures


Description

Meder Kydyraliev (Google Security) discovered an integer overflow vulnerability in the exif_data_load_data_thumbnail() function leading to a memory corruption (CVE-2007-6352) and an infinite recursion in the exif_loader_write() function (CVE-2007-6351).

Impact

An attacker could entice the user of an application making use of libexif 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.

Resolution

All libexif users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/libexif-0.6.16-r1"
