SynopsisThe remote machine is affected by a vulnerability.
DescriptionThe remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by a vulnerability:
- A use-after-free flaw can occur in the Linux kernel due to a race condition between packet_do_bind() and packet_notifier() functions called for an AF_PACKET socket. An unprivileged, local user could use this flaw to induce kernel memory corruption on the system, leading to an unresponsive system or to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. (CVE-2018-18559)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade the vulnerable CGSL kernel packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
