Technical description

On Linux the sccache client can execute arbitrary code with the privileges of a local sccache server, by preloading the code in a shared library passed to LD_PRELOAD.

If the server is run as root (which is the default when installing the snap package https://snapcraft.io/sccache ), this means a user running the sccache client can get root privileges.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
