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 flaw was discovered in the way the Linux kernel's TTY subsystem handled the tty shutdown phase. A local, unprivileged user could use this flaw to cause denial of service on the system by holding a reference to the ldisc lock during tty shutdown, causing a deadlock.(CVE-2015-4170)
