Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Link following

EUVDB-ID: #VU72246

Risk: Low

CVSSv4.0: 0.2 [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:U/U:Clear]

CVE-ID: CVE-2023-22490

CWE-ID: CWE-59 - Improper Link Resolution Before File Access ('Link Following')

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insecure processing of symbolic links when using local clone optimization. Git will abort local clones whose source `$GIT_DIR/objects` directory contains symbolic links, however the `objects` directory itself may still be a symbolic link. A remote attacker can trick the victim into using the local clone optimization to exfiltrate arbitrary files from the victim's system.

Mitigation

Install updates from vendor's repository.

2) 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

Description

The 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.

Mitigation

Install updates from vendor's repository.
