medium Tenable Self-Hosted Container Security Plugin ID 455434

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in p11-kit. A local attacker, or one with equivalent access to a reachable RPC channel,
 could exploit an integer overflow vulnerability. By sending specially crafted messages, the attacker can
 cause the system to miscalculate memory allocation for nested attributes. This leads to a memory
 corruption issue, specifically a heap out-of-bounds write, which can crash the p11-kit RPC parsing
 process, resulting in a Denial of Service (DoS). This vulnerability is only exploitable on 32 bit systems.
 (CVE-2026-18938)

Solution

Update the p11-kit library and its related packages to version 0.25.5-3+e2 or later.
