Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Error Handling (CVE-ID: CVE-2023-23931)

The vulnerability allows an attacker to misuse Python API.

The vulnerability exists due to a soundness bug within the Cipher.update_into function, which can allow immutable objects (such as bytes) to be mutated. A malicious programmer can misuse Python API to introduce unexpected behavior into the application.


2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-24998)

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

The vulnerability exists due to Apache Commons FileUpload does not limit the number of request parts. A remote attacker can initiate a series of uploads and perform a denial of service (DoS) attack.


3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-23916)

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

The vulnerability exists due to incorrect implementation of the "chained" HTTP compression algorithms, where the number of links in the decompression chain was limited for each header instead of the entire request. A remote attacker can send a specially crafted compressed HTTP request with numerous headers and perform a denial of service (DoS) attack.


4) Integer overflow (CVE-ID: CVE-2022-47629)

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

The vulnerability exists due to integer overflow in the CRL signature parser. 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.
