Security Bulletin

This security bulletin contains information about 5 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

Description

The 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.

Mitigation

Update the affected packages.
x11-libs/libXpm to version: 3.5.17

Vulnerable software versions

Gentoo Linux: All versions

x11-libs/libXpm: before 3.5.17

CPE2.3

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

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

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 packages.
x11-libs/libXpm to version: 3.5.17

Vulnerable software versions

Gentoo Linux: All versions

x11-libs/libXpm: before 3.5.17

CPE2.3

http://security.gentoo.org/glsa/202408-03

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

3) 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 packages.
x11-libs/libXpm to version: 3.5.17

Vulnerable software versions

Gentoo Linux: All versions

x11-libs/libXpm: before 3.5.17

CPE2.3

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.

4) Out-of-bounds read

EUVDB-ID: #VU81435

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-43788

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.
