CVE-2012-2812 [MEDIUM] libexif vulnerabilities
Title: libexif vulnerabilities
Summary: libexif could be made to crash, run programs as your login, or expose
sensitive information if it opened a specially crafted file.
Mateusz Jurczyk discovered that libexif incorrectly parsed certain
malformed EXIF tags. If a user or automated system were tricked into
processing a specially crafted image file, an attacker could cause libexif
to crash, leading to a denial of service, or possibly obtain sensitive
information. (CVE-2012-2812, CVE-2012-2813)

[MEDIUM] libexif security vulnerabilities
libexif security vulnerabilities
libexif ver. 0.6.20 and earlier suffers from a number of newly-discovered security vulnerabilities. The details will be made public with a new release of libexif that fixes them, which is planned to be the second week of July.
Very little has changed since version 0.6.20, so the new version should be a drop-in replacement. But, if you're interested in some advance testing, a prerelease version (that does NOT contain the security patches) is available at
http://sourceforge.net/projects/libexif/files/libexif/prerelease/libexif-0.6.21-pre1.tar.gz/download This prerelease should otherwise be substantially similar to the final release.
I'll update this bug with CVE numbers and more details before the release.
