Doc Text:	A vulnerability was found in fapolicyd. The vulnerability occurs due to an assumption on how glibc names the runtime linker, a build time regular expression may not correctly detect the runtime linker. The consequence is that the pattern detection for applications launched by the run time linker may fail to detect the pattern and allow execution.	Story Points:	---

Description Pedro Sampaio 2022-03-24 14:58:31 UTC

As a consequence of wrong dynamic preparation during the build time the fapolicyd service allows to execute any arbitrary code by unprivileged user if executed via the dynamic linker.
