Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Infinite loop
EUVDB-ID: #VU71235
Risk: Low
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-44617
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the ParsePixels() function when handling XPM files with width set to 0 and a very large height value. A remote attacker can trick the victim to open a specially crafted XPM file and perform a denial of service (DoS) attack.
