Qlustar Security Advisory 0703252

July 3rd, 2025

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.

This update includes several security related package updates from Debian/Ubuntu and AlmaLinux. The following list provides references to the upstream security report of the corresponding packages. You can view the original upstream advisory by clicking on the corresponding title.

Relevant to Qlustar 13 and 14 / Ubuntu

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

Sudo vulnerabilities

Rich Mirch discovered that Sudo incorrectly handled the host option. In environments where per-host rules are configured in the sudoers file, a local attacker could use this issue to bypass the host restrictions.

Qlustar 14 only: Rich Mirch discovered that Sudo incorrectly handled the chroot option. In environments where the sudoers file is configured to allow the chroot option, a local attacker could use this issue to run arbitrary commands as root.

libarchive vulnerabilities

It was discovered that libarchive incorrectly handled certain RAR archive files. An attacker could possibly use this issue to execute arbitrary code or cause a denial of service.

It was discovered that libarchive incorrectly handled certain RAR archive files. An attacker could possibly use this issue to read sensitive data or cause a denial of service.

It was discovered that libarchive incorrectly handled certain WARC archive files. If a user or automated system were tricked into processing a specially crafted WARC archive, an attacker could use this issue to cause libarchive to crash, resulting in a denial of service.

It was discovered that libarchive incorrectly handled certain file names when handling prefixes and suffixes. An attacker could possibly use this issue to cause libarchive to crash, resulting in a denial of service.

Python vulnerabilities

Qlustar 14 only: It was discovered that Python incorrectly handled tar archive extraction with the filtering option. An attacker could possibly use this issue to modify files in arbitrary filesystem locations and cause data loss.

PAM vulnerability

Olivier BAL-PETRE discovered that the PAM pam_namespace module incorrectly handled user-controlled paths. In environments where pam_namespace is used, a local attacker could possibly use this issue to escalate their privileges to root.

X.Org X Server vulnerabilities

Nils Emmerich discovered that the X.Org X Server incorrectly handled certain memory operations. An attacker could use these issues to cause the X Server to crash, leading to a denial of service, obtain sensitive information, or possibly execute arbitrary code.

Python vulnerabilities

It was discovered that Python incorrectly handled certain unicode characters during decoding. An attacker could possibly use this issue to cause a denial of service.

It was discovered that Python incorrectly handled unicode encoding of email headers with list separators in folded lines. An attacker could possibly use this issue to expose sensitive information.

systemd vulnerability

Qualys discovered that systemd incorrectly handled metadata when processing application crashes. An attacker could possibly use this issue to expose sensitive information.

MariaDB vulnerabilities

Qlustar 14 only: Several security issues were discovered in MariaDB and this update includes a new upstream MariaDB version to fix these issues.

In addition to security fixes, the updated packages contain bug fixes, new features, and possibly incompatible changes.

GNU C Library vulnerability

Qlustar 13 only: It was discovered that the GNU C Library incorrectly search LD_LIBRARY_PATH to determine which library to load when statically linked setuid binary calls dlopen. A local attacker could possibly use this issue to cause a denial of service or execute arbitrary code.

net-tools vulnerability

It was discovered that net-tools incorrectly handled certain inputs. An attacker could possible use this issue to cause a crash or execute arbitrary code.

GLib vulnerability

It was discovered that Glib incorrectly handled certain inputs. An attacker could possibly use this issue to cause a crash or execute arbitrary code.

MariaDB vulnerabilities

Qlustar 13 only: Several security issues were discovered in MariaDB and this update includes a new upstream MariaDB version to fix these issues.

In addition to security fixes, the updated packages contain bug fixes, new features, and possibly incompatible changes.

AlmaLinux 8.10 security updates
