3. Description:

 

The Simple Protocol for Independent Computing Environments (SPICE) is a

remote display system built for virtual environments which allows the user

to view a computing 'desktop' environment not only on the machine where it

is running, but from anywhere on the Internet and from a wide variety of

machine architectures.

 

Security Fix(es):

 

* A vulnerability was discovered in spice in the server's protocol

handling. An authenticated attacker could send crafted messages to the

spice server causing a heap overflow leading to a crash or possible code

execution. (CVE-2016-9577)

 

* A vulnerability was discovered in spice in the server's protocol

handling. An attacker able to connect to the spice server could send

crafted messages which would cause the process to crash. (CVE-2016-9578)

 

These issues were discovered by Frediano Ziglio (Red Hat).
