EulerOS Virtualization 3.0.6.6 : keepalived (EulerOS-SA-2020-2445)

medium Nessus Plugin ID 142505

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 - keepalived 2.0.8 didn't check for existing plain files when writing data to a temporary file upon a call to PrintData or PrintStats. If a local attacker had previously created a file with the expected name (e.g., /tmp/keepalived.data or /tmp/keepalived.stats), with read access for the attacker and write access for the keepalived process, then this potentially leaked sensitive information.(CVE-2018-19046)

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.
