8.4 HighFix available

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.

Moderate: fapolicyd security, bug fix, and enhancement update

Fapolicyd (File Access Policy Daemon) implements application whitelisting to decide file access rights. Applications that are known via a reputation source are allowed access while unknown applications are not. The daemon makes use of the kernel's fanotify interface to determine file access rights.

The following packages have been upgraded to a later upstream version: fapolicyd (1.1). (BZ#1939379)

Security Fix(es):

  • fapolicyd: fapolicyd wrongly prepares ld.so path (CVE-2022-1117)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
