"CVE-2017-17432 It was discovered that malformed jumbogram packets
could result in denial of service against OpenAFS, an implementation
of the Andrew distributed file system.

For Debian 7 'Wheezy', these problems have been fixed in version
1.6.1-3+deb7u8.

We recommend that you upgrade your openafs packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
