attacker could abuse an unvalidated usage of this function to cause a
denial of service or potentially lead to data leak. (CVE-2017-12613)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

Applications using the APR libraries, such as httpd, must be restarted for
this update to take effect.
