An update is available for trousers.
This update affects Rocky Linux 8.
A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE list
TrouSerS is an implementation of the Trusted Computing Group’s Software Stack (TSS) specification. TrouSerS enables the user to write applications that make use of the Trusted Platform Module (TPM) hardware.

The following packages have been upgraded to a later upstream version: trousers (0.3.15). (BZ#1725782)

Security Fix(es):

  • trousers: tss user still has read and write access to the /etc/tcsd.conf file if tcsd is started as root (CVE-2020-24331)

  • trousers: tss user can be used to create or corrupt existing files, this could lead to DoS (CVE-2020-24332)

  • trousers: fails to drop the root gid privilege when no longer needed (CVE-2020-24330)
