libexif fails to validate certain inputs, making it vulnerable to buffer overflows.
|Package||media-libs/libexif on all architectures|
|Affected versions||< 0.5.12-r1|
|Unaffected versions||>= 0.5.12-r1|
libexif is a library for parsing, editing and saving EXIF data.
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.
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.
There is no known workaround at this time.
All libexif users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libexif-0.5.12-r1"
