Name of the Vulnerable Software and Affected Versions
spice-vdagent versions 0.20 and previous versions
Description
A flaw was found in the way the spice-vdagentd daemon handled file transfers from the host system to the virtual machine. Any unprivileged local guest user with access to the UNIX domain socket path
/run/spice-vdagentd/spice-vdagent-sock could use this flaw to perform a memory denial of service for spice-vdagentd or even other processes in the VM system. The highest threat from this vulnerability is to system availability.Recommendations
For spice-vdagent versions 0.20 and previous versions, update to a version newer than 0.20 to resolve the issue.
As a temporary workaround, consider restricting access to the UNIX domain socket path
/run/spice-vdagentd/spice-vdagent-sock to minimize the risk of exploitation.Exploit
