GLSA-200503-17 : libexif: Buffer overflow vulnerability
Low Nessus Plugin ID 17319
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200503-17 (libexif: Buffer overflow vulnerability)
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.
SolutionAll libexif users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libexif-0.5.12-r1'
