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.
The product makes files or directories accessible to unauthorized actors, even though they should not be.

Web servers, FTP servers, and similar servers may store a set of files underneath a “root” directory that is accessible to the server’s users. Applications may store sensitive files underneath this root without also using access control to limit which users may request those files, if any. Alternately, an application might package multiple files or directories into an archive file (e.g., ZIP or tar), but the application might not exclude sensitive files that are underneath those directories. In cloud technologies and containers, this weakness might present itself in the form of misconfigured storage accounts that can be read or written by a public or anonymous user.
