Description
This security bulletin contains information about 1 security vulnerability.
1) Out-of-bounds read (CVE-ID: CVE-2017-6335)
The vulnerability allows a remote attacker to gain access to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the coders/tiff.c function in GraphicsMagick 1.3.25 and earlier allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a small samples per pixel value file. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and crash the affected application.
