libexif is a library for parsing, editing and saving Exif data.
Victor Stinner reported an integer overflow in the exif_data_load_data_entry() function from file exif-data.c while handling Exif data.
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.
There is no known workaround at this time.
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
