Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2022-39209)

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

The vulnerability exists due to a polynomial time complexity issue in the autolink extension. A remote user can trigger resource exhaustion and perform a denial of service (DoS) attack.


2) Inefficient Algorithmic Complexity (CVE-ID: CVE-2023-22483)

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

The vulnerability exists due to several polynomial time complexity issues. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


3) Inefficient Algorithmic Complexity (CVE-ID: CVE-2023-22484)

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

The vulnerability exists due to a polynomial time complexity issue in cmark-gfm may in handle_pointy_brace. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


4) Inefficient Algorithmic Complexity (CVE-ID: CVE-2023-22486)

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

The vulnerability exists due to a polynomial time complexity issue in cmark-gfm in handle_close_bracket. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


5) Inefficient Algorithmic Complexity (CVE-ID: CVE-2023-26485)

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

The vulnerability exists due to the polynomial time complexity issue. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
