FKIE_CVE-2023-1521

Vulnerability from fkie_nvd - Published: 2024-11-26 12:15 - Updated: 2026-06-17 05:28
Severity
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
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.
