This release fixes CVE-2020-14392 (a memory corruption in XS functions when Perl stack is reallocated), CVE-2019-20919 (a NULL profile dereference in dbi_profile()), a documentation that old API functions are vulnerable to an overflow, and CVE-2020-14393 (a buffer overlfow on an overlong DBD class name). It also adds a missing dependency on FileHandle Perl module.
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.
