Updated spice packages fix security vulnerabilities

Publication date: 08 Jul 2016
Type: security
Affected Mageia releases : 5
CVE: CVE-2016-0749 , CVE-2016-2150


Updated spice packages fix security vulnerabilities:

A memory allocation flaw, leading to a heap-based buffer overflow, was found in
spice's smartcard interaction, which runs under the QEMU-KVM context on the
host. A user connecting to a guest VM using spice could potentially use this
flaw to crash the QEMU-KVM process or execute arbitrary code with the privileges
of the host's QEMU-KVM process (CVE-2016-0749).

A memory access flaw was found in the way spice handled certain guests using
crafted primary surface parameters. A user in a guest could use this flaw to
read from and write to arbitrary memory locations on the host (CVE-2016-2150).
