Universal components / Libraries /
Libraries used by multiple products
Vendor: GraphicsMagick Group
Description
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists in the DescribeImage function of the magick/describe.c file due to heap-based buffer over-read because the portion of the code containing the vulnerability is responsible for printing the IPTC Profile information contained in the image and out-of-bounds buffer dereference because certain increments are never checked. A remote attacker can trick the victim into opening a specially crafted MIFF file and gain access to potentially sensitive information.
Mitigation
Install update from vendor's website.
