Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Return of Wrong Status Code (CVE-ID: CVE-2025-5987)

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

The vulnerability exists due to incorrect handling of the wrong status code returned by the OpenSSL within the chacha20_poly1305_set_key() function when using the ChaCha20 cipher with the OpenSSL library. A remote attacker can force the library to partially initialize cipher context, leading to an undefined application's behavior.


2) Uncontrolled Recursion (CVE-ID: CVE-2025-9714)

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

The vulnerability exists due to uncontrolled recursion in XPath evaluation within the xmlXPathRunEval() function in xpath.c. A remote attacker can pass specially crated XML data to the application and perform a denial of service (DoS) attack.


3) Heap-based buffer overflow (CVE-ID: CVE-2025-11083)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the elf_swap_shdr() function in bfd/elfcode.h. A local user can trigger a heap-based buffer overflow and execute arbitrary code on the target system.
