CWE-ID: CWE-400

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
OpenJPEG
Universal components / Libraries / Libraries used by multiple products

Vendor: openjpeg.org

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper memory operations that are performed by the opj_calloc function, as defined in the openjp2/opj_malloc.c source code file when a call is made from the opj_tcd_init_tile function in the openjp2/tcd.c file. A remote attacker can trick the victim into executing an JPEG 2000 image file with a 64-bit opj_decompress program that submits malicious input, consume excessive amounts of memory resources and cause the affected application to hang.

Mitigation
Install update from vendor's website.

Vulnerable software versions
