It was possible to trigger a heap-based buffer overflow with an

crash.

For Debian 7 'Wheezy', these problems have been fixed in version
1.2.0-12+deb7u1.

We recommend that you upgrade your bchunk 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."
