NewStart CGSL MAIN 5.04 : kernel-rt Vulnerability (NS-SA-2019-0018)

high Nessus Plugin ID 127173

Synopsis

The remote machine is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 5.04, has kernel-rt packages installed that are affected by a vulnerability:

- A race condition was found in the Linux kernel, present since v3.14-rc1 through v4.12. The race happens between threads of inotify_handle_event() and vfs_rename() while running the rename operation against the same file. As a result of the race the next slab data or the slab's free list pointer can be corrupted with attacker-controlled data, which may lead to the privilege escalation.
(CVE-2017-7533)

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 kernel-rt packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
