"An issue in bsdiff, a tool to generate/apply a patch between two
binary files, has been found.

Using a crafted patch file an integer signedness error in bspatch
could be used for a heap based buffer overflow and possibly execution
of arbitrary code.

For Debian 8 'Jessie', this problem has been fixed in version
4.3-15+deb8u1.

We recommend that you upgrade your bsdiff 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.");
