ArchLinux: 201902-4: spice: arbitrary code execution
Summary
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.
Resolution
Upgrade to 0.14.0-3.
# pacman -Syu "spice>=0.14.0-3"
The problem has been fixed upstream but no release is available yet.
