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.
