CVSSv4: 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


The 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.


2) Infinite loop (CVE-ID: CVE-2022-46285)
