EulerOS 2.0 SP2 : kernel (EulerOS-SA-2017-1160)

high Nessus Plugin ID 102998

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the kernel packages installed, the EulerOS installation on the remote host is affected by the following 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. (CVE-2017-7533)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected kernel package.
