CWE-ID: CWE-125

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
ImageMagick
Client/Desktop applications / Multimedia software

Vendor: ImageMagick.org

Description

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 ImageMagick before 6.7.6-3 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted EXIF IFD 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.

Mitigation
Update to version 6.7.6-3.

Vulnerable software versions
