SUSE SLES11 Security Update : spice (SUSE-SU-2021:14744-1)

high Nessus Plugin ID 150653

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES11 / SLES_SAP11 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14744-1 advisory.

- SPICE allows local guest OS users to read from or write to arbitrary host memory locations via crafted primary surface parameters, a similar issue to CVE-2015-5261. (CVE-2016-2150)

- Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1. Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution.
(CVE-2020-14355)

- A flaw was found in spice in versions before 0.14.92. A DoS tool might make it easier for remote attackers to cause a denial of service (CPU consumption) by performing many renegotiations within a single connection. (CVE-2021-20201)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected libspice-server1 package.
