Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU73888
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-2022-38171
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the JBIG2 decoder in the JBIG2Stream::readTextRegionSeg() function in JBIG2Stream.cc. A remote attacker can pass a specially crafted PDF file or JBIG2 image to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
Note, the vulnerability is related to #VU56067 (CVE-2021-30860).
