Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) 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

Description

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.

Mitigation

Update the affected package libXpm to the latest version.

2) Infinite loop

EUVDB-ID: #VU71234

Risk: Low

CVSSv3.1: 3.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-46285

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop when handling unclosed comments in XPM images within the ParseComment() function. A remote attacker can trick the victim to open a specially crafted image and cause denial of service conditions.

Mitigation

Update the affected package libXpm to the latest version.
