    Several vulnerabilities were discovered in spice, a SPICE protocol
    client and server library. The Common Vulnerabilities and Exposures
    project identifies the following problems:
    
    CVE-2016-9577
    
        Frediano Ziglio of Red Hat discovered a buffer overflow
        vulnerability in the main_channel_alloc_msg_rcv_buf function. An
        authenticated attacker can take advantage of this flaw to cause a
        denial of service (spice server crash), or possibly, execute
        arbitrary code.
    
    CVE-2016-9578
    
        Frediano Ziglio of Red Hat discovered that spice does not properly
        validate incoming messages. An attacker able to connect to the
        spice server could send crafted messages which would cause the
        process to crash.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 0.12.5-1+deb8u4.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 0.12.8-2.1.
    
    We recommend that you upgrade your spice packages.
