EUVDB-ID: #VU33227

Risk: High

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2017-14151

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

An off-by-one error was discovered in opj_tcd_code_block_enc_allocate_data in lib/openjp2/tcd.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_mqc_flush in lib/openjp2/mqc.c and opj_t1_encode_cblk in lib/openjp2/t1.c) or possibly remote code execution.

Mitigation

Install update from vendor's website.
