EUVDB-ID: #VU33228

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-14152

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

A mishandled zero case was discovered in opj_j2k_set_cinema_parameters 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 and opj_j2k_write_sot in lib/openjp2/j2k.c) or possibly remote code execution.

Mitigation

Install update from vendor's website.
