Security Bulletin
This security bulletin contains information about 3 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
DescriptionThe 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.
Install updates from vendor's repository.

CVE-ID: CVE-2023-23946
CWE-ID:
CWE-59 - Improper Link Resolution Before File Access ('Link Following')
Exploit availability: No
DescriptionThe vulnerability allows an attacker to compromise the affected system.
The vulnerability exists due to application allows to overwrite files outside the working tree via the "git apply" command. A remote attacker can trick the victim to run the affected command against a malicious or compromised repository and overwrite arbitrary files on the system.

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.
