1) Buffer overflow

EUVDB-ID: #VU33223

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2017-12982

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.

The bmp_read_info_header function in bin/jp2/convertbmp.c in OpenJPEG 2.2.0 does not reject headers with a zero biBitCount, which allows remote attackers to cause a denial of service (memory allocation failure) in the opj_image_create function in lib/openjp2/image.c, related to the opj_aligned_alloc_n function in opj_malloc.c.

Mitigation

Install update from vendor's website.
