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. This flaw affects spice-vdagent versions 0.20 and previous versions. CVE-2020-25650 openSUSE Leap 15.3:spice-vdagent-0.21.0-3.3.1 moderate 2.1 AV:L/AC:L/Au:N/C:N/I:N/A:P To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://lists.opensuse.org/archives/list/security-announce@lists.opensuse.org/thread/UU4MAHRZUXACEK4PTFMFULLO5A7INQM5/ https://www.suse.com/security/cve/CVE-2020-25650.html CVE-2020-25650 https://bugzilla.suse.com/1177780 SUSE Bug 1177780 A flaw was found in the SPICE file transfer protocol. File data from the host system can end up in full or in parts in the client connection of an illegitimate local user in the VM system. Active file transfers from other users could also be interrupted, resulting in a denial of service. The highest threat from this vulnerability is to data confidentiality as well as system availability. This flaw affects spice-vdagent versions 0.20 and prior. CVE-2020-25651 openSUSE Leap 15.3:spice-vdagent-0.21.0-3.3.1 moderate 3.3 AV:L/AC:M/Au:N/C:P/I:N/A:P To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://lists.opensuse.org/archives/list/security-announce@lists.opensuse.org/thread/UU4MAHRZUXACEK4PTFMFULLO5A7INQM5/ https://www.suse.com/security/cve/CVE-2020-25651.html CVE-2020-25651 https://bugzilla.suse.com/1177781 SUSE Bug 1177781 A flaw was found in the spice-vdagentd daemon, where it did not properly handle client connections that can be established via the UNIX domain socket in `/run/spice-vdagentd/spice-vdagent-sock`. Any unprivileged local guest user could use this flaw to prevent legitimate agents from connecting to the spice-vdagentd daemon, resulting in a denial of service. The highest threat from this vulnerability is to system availability. This flaw affects spice-vdagent versions 0.20 and prior. CVE-2020-25652 openSUSE Leap 15.3:spice-vdagent-0.21.0-3.3.1 moderate 4.9 AV:L/AC:L/Au:N/C:N/I:N/A:C To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://lists.opensuse.org/archives/list/security-announce@lists.opensuse.org/thread/UU4MAHRZUXACEK4PTFMFULLO5A7INQM5/ https://www.suse.com/security/cve/CVE-2020-25652.html CVE-2020-25652 https://bugzilla.suse.com/1177782 SUSE Bug 1177782 A race condition vulnerability was found in the way the spice-vdagentd daemon handled new client connections. This flaw may allow an unprivileged local guest user to become the active agent for spice-vdagentd, possibly resulting in a denial of service or information leakage from the host. The highest threat from this vulnerability is to data confidentiality as well as system availability. This flaw affects spice-vdagent versions 0.20 and prior. CVE-2020-25653 openSUSE Leap 15.3:spice-vdagent-0.21.0-3.3.1 important 5.4 AV:L/AC:M/Au:N/C:P/I:N/A:C To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://lists.opensuse.org/archives/list/security-announce@lists.opensuse.org/thread/UU4MAHRZUXACEK4PTFMFULLO5A7INQM5/ https://www.suse.com/security/cve/CVE-2020-25653.html CVE-2020-25653 https://bugzilla.suse.com/1177783 SUSE Bug 1177783
