CVE-2023-1521

Date: November 26, 2024

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), this means a user running the sccache client can get root privileges. The vulnerability is fixed in version 0.4.0.
