EulerOS Virtualization for ARM 64 3.0.2.0 : keepalived (EulerOS-SA-2020-1561)

medium Nessus Plugin ID 136264

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing a security update.

Description

According to the version of the keepalived package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

 - keepalived 2.0.8 didn't check for pathnames with symlinks when writing data to a temporary file upon a call to PrintData or PrintStats. This allowed local users to overwrite arbitrary files if fs.protected_symlinks is set to 0, as demonstrated by a symlink from /tmp/keepalived.data or /tmp/keepalived.stats to /etc/passwd.(CVE-2018-19044)

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 keepalived package.
