Gentoo Linux Security Advisory

Title: Exiv2: Integer overflow (GLSA 200712-16)
Severity: normal
Exploitable: remote
Date: December 29, 2007
Bug(s): #202351
ID: 200712-16

Synopsis


An integer overflow vulnerability in Exiv2 possibly allows for the
execution of arbitrary code.


Background


Exiv2 is a C++ library and set of tools for parsing, editing and saving
Exif and IPTC 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-gfx/exiv2
Vulnerable: < 0.13-r1
Unaffected: >= 0.13-r1
Architectures: All supported architectures


Description


Meder Kydyraliev (Google Security) discovered an integer overflow
vulnerability in the JpegThumbnail::setDataArea() method leading to a
heap-based buffer overflow.


Impact


An attacker could entice the user of an application making use of Exiv2
or an application included in Exiv2 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.


Workaround


There is no known workaround at this time.


Resolution


All Exiv2 users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/exiv2-0.13-r1"


References

CVE-2007-6353
