This release provides Perl 5.24.4 that fixes a heap buffer overflow in the pack() function and two overflows in the regular expression engine.
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
