Name of the Vulnerable Software and Affected Versions sccache versions prior to 0.4.0

Description 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, this means a user running the sccache client can get root privileges.

Recommendations Upgrade to version 0.4.0 As a temporary workaround, do not run the sccache server as root.
