Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2023-45142)

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

The vulnerability exists due to incorrect processing of HTTP header User-Agent and HTTP method. A remote attacker can send multiple requests with long randomly generated HTTP methods or/and User agents and consume memory resources, leading to a denial of service condition.

2) Use of Hard-coded Cryptographic Key (CVE-ID: CVE-2023-46129)

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

The vulnerability exists due to the usage of a hard-coded cryptograhic key. A remote attacker can gain unauthorized access to sensitive information on the system.


3) Path traversal (CVE-ID: CVE-2007-4559)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to improper validation of filenames in the tarfile module in Python. A remote attacker can create a specially crafted archive with symbolic links inside or filenames that contain directory traversal characters (e.g. "..") and overwrite arbitrary files on the system.


4) Information disclosure (CVE-ID: CVE-2023-4641)

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to an error in gpasswd(1), which fails to clean memory properly. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. A local user with enough access can retrieve the password from the memory.


5) Buffer overflow (CVE-ID: CVE-2023-22745)

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

The vulnerability exists due to a boundary error in "Tss2_RC_SetHandler" and "Tss2_RC_Decode". A remote attacker can trigger memory corruption and execute arbitrary code on the target system.

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