CVE-2023-1521 (GCVE-0-2023-1521)

Vulnerability from cvelistv5 – Published: 2024-11-26 11:15 – Updated: 2024-11-26 20:45
VLAI?
Summary
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.
Severity ?
7.8 (High)
