Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Incorrect Regular Expression (CVE-ID: CVE-2024-4067)

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

The vulnerability occurs in `micromatch.braces()` in `index.js` because the pattern `.*` will greedily match anything. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.


2) Input validation error (CVE-ID: CVE-2024-24789)

The vulnerability allows a remote attacker to manipulate data.

The vulnerability exists due to insufficient validation of user-supplied input in archive/zip when handling zip archives. A remote attacker can create a zip file with content that will vary depending on the implementation reading the file.


3) Input validation error (CVE-ID: CVE-2024-24790)

The vulnerability allows a remote attacker to modify application behavior.

The vulnerability exists due to improper handling of IPv4-mapped IPv6 addresses in net/netip within multiple methods, e.g. IsPrivate, IsLoopback. The affected methods return false for addresses which would return true in their traditional IPv4 forms, leading to potential bypass of implemented security features.


4) Incorrect Regular Expression (CVE-ID: CVE-2024-39249)

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

The vulnerability exists due to insufficient input validation when processing regular expressions. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.


5) Insecure Storage of Sensitive Information (CVE-ID: CVE-2024-10041)

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

The vulnerability exists due to software stores secrets in memory in plain text. A local user can read the memory and obtain passwords in plain text when PAM is used to perform authentication.


6) Improper authentication (CVE-ID: CVE-2024-10963)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in pam_access module where certain rules in its configuration file are mistakenly treated as hostnames. A remote attacker can bypass authentication process and gain unauthorized access to the system.
