Summary: Updated spice packages fix security vulnerability

Details: Spice, versions 0.5.2 through 0.14.1, are vulnerable to an out-of-bounds read due to an off-by-one error in memslot_get_virt. This may lead to a denial of service, or, in the worst case, code-execution by unauthenticated attackers. (CVE-2019-3813) 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. (CVE-2018-10873) Multiple integer overflow and buffer overflow issues were discovered in spice-client's handling of LZ compressed frames. A malicious server could cause the client to crash or, potentially, execute arbitrary code. (CVE-2018-10893)
