EulerOS Virtualization 2.5.2 : systemd (EulerOS-SA-2019-1063)

high Nessus Plugin ID 122459

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 - In systemd through 233, certain sizes passed to dns_packet_new in systemd-resolved can cause it to allocate a buffer that's too small. A malicious DNS server can exploit this via a response with a specially crafted TCP payload to trick systemd-resolved into allocating a buffer that's too small, and subsequently write arbitrary data beyond the end of it.(CVE-2017-9445)

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 systemd package.
