Synopsis

The remote Debian host is missing a security update.

Description

Moshe Kol and Shlomi Oberman of JSOF discovered several vulnerabilities in dnsmasq, a small caching DNS proxy and DHCP/TFTP server. They could result in denial of service, cache poisoning or the execution of arbitrary code.

For Debian 9 stretch, these problems have been fixed in version 2.76-5+deb9u3.

We recommend that you upgrade your dnsmasq packages.

For the detailed security status of dnsmasq please refer to its security tracker page at:

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

Solution

Upgrade the affected packages.
