Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2022-25147)

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

The vulnerability exists due to integer overflow within the apr_base64() function. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.

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


2) Link following (CVE-ID: CVE-2023-22490)

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.


3) Input validation error (CVE-ID: CVE-2022-39253)

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.


4) Link following (CVE-ID: CVE-2023-23946)

The 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.


5) Information disclosure (CVE-ID: CVE-2022-44268)

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

The vulnerability exists due to improper input validation when performing operations (e.g. resizing) on specially crafted PNG images. A remote attacker can pass a specially crafted image to the application and embed contents of other files on the system into the resulting image.


6) Resource management error (CVE-ID: CVE-2022-44267)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources when performing operations on crafted PNG images. A remote attacker can pass specially crafted PNG image to the application and force the application to wait indefinitely for the stdin input, consuming system resources.
