Red Hat Product Errata RHSA-2012:1255 0 normal SHIPPED_LIVE Moderate: libexif security update 2012-09-11 22:12:47 UTC

Description Stefan Cornelius 2012-07-11 08:21:16 UTC
A heap-based out-of-bounds array read in the exif_entry_get_value function in libexif/exif-entry.c in libexif 0.6.20 and earlier allows remote attackers to cause a denial of service or possibly obtain potentially sensitive information from process memory via an image with crafted EXIF tags.
