CWE-ID: CWE-119

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 non-authenticated attacker to execute arbitrary code.

A size-validation issue was discovered in opj_j2k_write_sot in lib/openjp2/j2k.c in OpenJPEG 2.2.0. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service (heap-based buffer overflow affecting opj_write_bytes_LE in lib/openjp2/cio.c) or possibly remote code execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-14152.

Mitigation
Install update from vendor's website.
