"A vulnerability was discovered in SPICE before version 0.14.1 where
the generated code used for demarshalling messages lacked sufficient
bounds checks. A malicious client or server, after authentication,
could send specially crafted messages to its peer which would result
in a crash or, potentially, other impacts.

The issue has been fixed by upstream by bailing out with an error if
the pointer to the start of some message data is strictly greater than
the pointer to the end of the message data.

For Debian 8 'Jessie', this problem has been fixed in version
0.12.5-1+deb8u6.

We recommend that you upgrade your spice packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
