Synopsis

Description

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dla-4221 advisory.

 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-4221-1 [email protected] https://www.debian.org/lts/security/ Thorsten Alteholz June 17, 2025 https://wiki.debian.org/LTS
 - -------------------------------------------------------------------------

 Package : libblockdev Version : 2.25-2+deb11u1 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 Debian 11 bullseye, this problem has been fixed in version 2.25-2+deb11u1.

 We recommend that you upgrade your libblockdev packages.

 For the detailed security status of libblockdev please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/libblockdev

 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian 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

Upgrade the gir1.2-blockdev-2.0 packages.
