Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Integer overflow

EUVDB-ID: #VU71239

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-23521

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to insufficient validation of user-supplied input when parsing the .gitattributes attributes. A remote attacker can trick the victim into cloning a specially crafted repository and execute arbitrary code on the system.

Mitigation

Update the affected package git to the latest version.

2) Heap-based buffer overflow

EUVDB-ID: #VU71238

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-41903

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error during git archive invocation. A remote attacker can trick the victim into using the application against a specially crafted archive, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected package git to the latest version.
