Synopsis ========
libexif fails to validate certain inputs, making it vulnerable to buffer overflows.
Background ==========
libexif is a library for parsing, editing and saving EXIF data.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/libexif < 0.5.12-r1 >= 0.5.12-r1
Description ===========
libexif contains a buffer overflow vulnerability in the EXIF tag validation code. When opening an image with a specially crafted EXIF tag, the lack of validation can cause applications linked to libexif to crash.
Impact ======
A specially crafted EXIF file could crash applications making use of libexif, potentially allowing 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 libexif users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libexif-0.5.12-r1"
