Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5943 advisory.

 - ------------------------------------------------------------------------- Debian Security Advisory DSA-5943-1 [email protected] https://www.debian.org/security/ Salvatore Bonaccorso June 17, 2025 https://www.debian.org/security/faq
 - -------------------------------------------------------------------------

 Package : libblockdev CVE ID : CVE-2025-6019

 The Qualys Threat Research Unit (TRU) discovered a local privilege escalation vulnerability in libblockdev, a library for manipulating block devices. An allow_active user can exploit this flaw via the udisks daemon to obtain the full privileges of the root user.

 Details can be found in the Qualys advisory at https://www.qualys.com/2025/06/17/suse15-pam-udisks-lpe.txt

 Along with the libblockdev update, updated udisks2 packages are released, to enforce that private mounts are mounted with 'nodev,nosuid'.

 For the stable distribution (bookworm), this problem has been fixed in version 2.28-2+deb12u1. The additional udisks2 hardening is applied in version 2.9.4-4+deb12u1.

 We recommend that you upgrade your libblockdev packages.

 For the detailed security status of libblockdev please refer to its security tracker page at:
