Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2017-6335)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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.
