CVE-2023-1521 Information

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.
