No, it is not mentioned there.  What that link says is:

The file has "libpcap" in its name, but it is *not* part of libpcap.  Wireshark has its own code to read libpcap, a/k/a 
pcap, files, and the bug was in *that* code.  It's a Wireshark bug, not a libpcap bug.

The bug report for that appears to be

        https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9753

and it has two test captures attached to it; libpcap does not crash with either of them.

No version of libpcap is vulnerable.

There's no bug in libpcap, so there's no fix to be made.
