openSUSE 16 Security Update : openCryptoki (openSUSE-SU-2026:20699-1)

medium Nessus Plugin ID 313703

Synopsis

The remote openSUSE host is missing a security update.

Description

The remote openSUSE 16 host has packages installed that are affected by a vulnerability as referenced in the openSUSE- SU-2026:20699-1 advisory.

 This update for openCryptoki fixes the following issues

 Security issue:

 - CVE-2026-40253: Updated fix for malformed BER-encoded cryptographic objects (bsc#1262283).

 Non security issue:

 - Refactored .spec file to fully support transactional and immutable operating systems (jsc#PED-14609):
 * Migrated user and group creation (pkcs11, pkcsslotd) from imperative %pre shell commands to declarative systemd-sysusers configuration.
 * Replaced manual /var directory tracking and %ghost directives with comprehensive systemd-tmpfiles configurations.
 * Implemented dynamic, architecture-specific tmpfiles.d generation to properly provision hardware-specific token directories (e.g., ccatok, ep11tok, lite, and HSM_MK_CHANGE).
 - Fixed permissions for /run/opencryptoki within tmpfiles.d to ensure the daemon can successfully drop privileges and bind its communication socket.
 * Moved 32-bit and 64-bit shared library symlink creation (such as PKCS11_API.so, stdll, and methods) from %post scriptlets into the %install phase, ensuring they are correctly packaged and tracked on the read-only /usr partition.
 * Removed legacy /etc/pkcs11 bash migration logic from %post, replacing it with a declarative tmpfiles.d symlink rule.
 - Cleaned up scriptlets to only execute transaction-safe macros (such as ldconfig and systemd service handlers).

Tenable has extracted the preceding description block directly from the SUSE 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 openCryptoki, openCryptoki-64bit and / or openCryptoki-devel packages.
