Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Untrusted search path
EUVDB-ID: #VU71236
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-4883
CWE-ID:
CWE-426 - Untrusted Search Path
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to libXpm relies on the $PATH variable to run the command responsible for decompressing .Z or .gz files. A local user can execute arbitrary code with elevated privileges.
Install update from vendor's website.

2) Infinite loop
EUVDB-ID: #VU71235
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
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.
