CVE-2020-24332: n/a vulnerability

CVE-2020-24332: An issue was discovered in TrouSerS through 0.3.14.

An issue was discovered in TrouSerS through 0.3.14. If the tcsd daemon is started with root privileges, the creation of the system.data file is prone to symlink attacks. The tss user can be used to create or corrupt existing files, which could possibly lead to a DoS attack.

Security readout for executives and security teams

TrouSerS tcsd through 0.3.14 can mishandle creation of system.data when running as root. A local tss user could abuse symlinks to create or corrupt files, potentially causing disruption. This is mainly an operational integrity and availability risk, not confirmed remote compromise. Exposure is likely limited to systems with TrouSerS through 0.3.14 installed and the tcsd TPM 1.2 daemon running with root privileges. Risk depends on local account access and whether the tss user or service account can be abused. Treat as a targeted hygiene fix for Linux systems using TrouSerS TPM 1.2 services. It is not supported as internet-scale emergency risk by the provided sources, but file corruption under a root daemon is enough to prioritize patching in managed server fleets. Mitigation focus: Check vendor advisories for updated TrouSerS packages or backported fixes.; Prioritize Fedora, SUSE, and upstream guidance referenced in the source bundle.; Avoid running affected tcsd configurations where they are not required..
