Qlustar Security Advisory 0822262

August 22nd, 2026

Summary:

A Qlustar security update bundle is a cumulative update of packages that are taken from upstream Debian/Ubuntu without modification. Only packages that are used in a typical HPC/Storage cluster installation are mentioned in Qlustar Security Advisories. Other non-HPC related updates also enter the Qlustar repository, but their functionality is not separately verified by the Qlustar team. To track these updates subscribe to the general security mailing lists of Debian/Ubuntu and/or AlmaLinux.

Relevant to Qlustar 13 and/or 14 – Ubuntu

If an advisory applies only to Qlustar 13 or 14, it is noted in its description.

Vim vulnerabilities

It was discovered that Vim incorrectly handled memory when decoding certain JSON input. An attacker could possibly use this issue to cause Vim to crash, resulting in a denial of service.

Yazan Balawneh discovered that Vim incorrectly handled memory when opening certain spell files. An attacker could possibly use this issue to cause Vim to crash, resulting in a denial of service, or possibly execute arbitrary code.

It was discovered that Vim incorrectly handled memory when processing certain files with a large number of text properties. An attacker could possibly use this issue to cause Vim to crash, resulting in a denial of service, or possibly execute arbitrary code.

It was discovered that Vim incorrectly handled certain vimball files. An attacker could possibly use this issue to execute arbitrary code.

It was discovered that Vim incorrectly handled shell arguments during keyword lookups. An attacker could possibly use this issue to execute arbitrary code.

David Carliez discovered that Vim incorrectly handled certain directory paths when constructing netrw menus. An attacker could possibly use this issue to execute arbitrary code.

curl vulnerability

It was discovered that curl incorrectly handled reusing connections when the origin changed between transfers. A remote attacker could possibly use this issue to obtain sensitive information.

libpng vulnerabilities

Seung Min Shin discovered that libpng incorrectly handled certain animated images. An attacker could possibly use this issue to cause libpng to misinterpret image data. This issue only affected Qlustar 13.

systemd vulnerabilities

It was discovered that systemd-homed did not properly verify the signature of home records. A local attacker could possibly use this issue to add arbitrary system groups to a logged-in user and gain elevated privileges.

It was discovered that systemd-oomd did not properly validate certain IPC requests. A local attacker could possibly use this issue to terminate arbitrary processes.

AlmaLinux 8.10 security updates

Please check the AlmaLinux Errata site for details about AlmaLinux 8 updates that entered this release (everything from August 7th until August 21st).

Update instructions:

The problem can be corrected by updating your system to the following or more recent package versions:

For Qlustar 14

qlustar-module-core-noble-amd64-14.1       14.1.10-b589f1643
qlustar-module-core-centos8-amd64-14.1     14.1.10-b589f1643

For Qlustar 13

qlustar-module-core-jammy-amd64-13.4       13.4.9-b588f1642

Special Update instructions:

In addition to the steps described in the general Qlustar Update Instructions these updates require the following:

• Spack migration With the release of the HPC Core Stack 02/26, spack was also updated to version 1.1.1. If you haven’t yet migrated your spack database to version 8, login on a cluster node as a user with Spack admin rights (usually user softadm or anybody in the group softadm) and execute

  # spack reindex
  

  Note that after this, older Spack versions will no longer be able to read the database. However, a backup is created in case a revert is needed.

• Please note that we no longer provide 13.x AlmaLinux 8 modules for Qlustar 13. If you want to use AlmaLinux 8 under Qlustar 13, please switch to the 14.x image modules and create a corresponding chroot for it.
