high Nessus Plugin ID 127410

Language:

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 4.05, has spice-server packages installed that are affected by multiple vulnerabilities:

 - A vulnerability was discovered in spice server's protocol handling. An authenticated attacker could send specially crafted messages to the spice server, causing out-of-bounds memory accesses, leading to parts of server memory being leaked or a crash. (CVE-2017-7506)

 - A vulnerability was discovered in SPICE where the generated code used for demarshalling messages lacked sufficient bounds checks. A malicious client or server, after authentication, could send specially crafted messages to its peer which would result in a crash or, potentially, other impacts. (CVE-2018-10873)

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

Solution

Upgrade the vulnerable CGSL spice-server packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
