[QSA-0114192] Security Update Bundle

Qlustar Security Advisory 01141912

Jan 14th, 2019


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.

This update includes several security related package updates from Debian/Ubuntu. 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.

systemd vulnerabilities

It was discovered that systemd-journald allocated variable-length buffers for certain message fields on the stack. A local attacker could potentially exploit this to cause a denial of service, or execute arbitrary code.

It was discovered that systemd-journald allocated variable-length arrays of objects representing message fields on the stack. A local attacker could potentially exploit this to cause a denial of service, or execute arbitrary code.

An out-of-bounds read was discovered in systemd-journald. A local attacker could potentially exploit this to obtain sensitive information and bypass ASLR protections.

nss vulnerabilities

Keegan Ryan discovered that NSS incorrectly handled ECDSA key generation. A local attacker could possibly use this issue to perform a cache-timing attack and recover private ECDSA keys.

It was discovered that NSS incorrectly handled certain v2-compatible ClientHello messages. A remote attacker could possibly use this issue to perform a replay attack.

It was discovered that NSS incorrectly handled certain padding oracles. A remote attacker could possibly use this issue to perform a variant of the Bleichenbacher attack.
