Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Infinite loop

EUVDB-ID: #VU86202

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-24575

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 in git_revparse_single within the revparse() function in src/libgit2/revparse.c. A remote attacker can consume all available system resources and cause denial of service conditions.

Mitigation

Update the affected package libgit2 to the latest version.

2) Heap-based buffer overflow

EUVDB-ID: #VU86201

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-24577

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 in git_index_add. A remote attacker can pass specially crafted filename that starts with a "/" character to the application, 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 libgit2 to the latest version.
