Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU68517
Risk: Low
CVSSv4.0: 0.9 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2022-39253
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to the way Git handles hardlinks when performing a local clone. A remote attacker can trick the victim into clocking a malicious repository and create or copy hardlinks to critical files on the system, which can result in sensitive information exposure.
Update the affected package git to the latest version.

2) Heap-based buffer overflow
EUVDB-ID: #VU68518
Risk: High
CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2022-39260
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the "git shell" command when handling untrusted input. A remote attacker can trick the victim to execute the affected command against a malicious repository, 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.
MitigationUpdate the affected package git to the latest version.
