EulerOS 2.0 SP15 : p11-kit (EulerOS-SA-2026-3996)

medium Nessus Plugin ID 364000

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the p11-kit packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

A flaw was found in p11-kit. The RPC message attribute parsing functions p11_rpc_message_get_attribute() and p11_rpc_message_get_attribute_array_value() form a mutually-recursive call chain with no recursion depth limit when processing nested CKA_WRAP_TEMPLATE, CKA_UNWRAP_TEMPLATE, and CKA_DERIVE_TEMPLATE attributes. An unauthenticated attacker with local access to the p11-kit RPC Unix domain socket can send a specially crafted request with deeply nested template attributes, causing stack exhaustion and crashing the p11-kit server process and its dependent services.(CVE-2026-13757)

Tenable has extracted the preceding description block directly from the EulerOS p11-kit security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected p11-kit packages.
