GLSA-200706-01 : libexif: Integer overflow vulnerability

high Nessus Plugin ID 25438

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200706-01 (libexif: Integer overflow vulnerability)

 Victor Stinner reported an integer overflow in the exif_data_load_data_entry() function from file exif-data.c while handling Exif data.
 Impact :

 An attacker could entice a user to process a file with specially crafted Exif extensions with an application making use of libexif, which will trigger the integer overflow and potentially execute arbitrary code or crash the application.
 Workaround :

 There is no known workaround at this time.

Solution

All libexif users should upgrade to the latest version. Please note that users upgrading from '<=media-libs/libexif-0.6.13' should also run revdep-rebuild after their upgrade.
 # emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libexif-0.6.15' # revdep-rebuild --library=/usr/lib/libexif.so
