CVE-2015-3294  (opens in a new tab)
CWE-19  (opens in a new tab)

How to fix?

Upgrade Debian:8 dnsmasq to version 2.72-3+deb8u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream dnsmasq package and not the dnsmasq package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

The tcp_request function in Dnsmasq before 2.73rc4 does not properly handle the return value of the setup_reply function, which allows remote attackers to read process memory and cause a denial of service (out-of-bounds read and crash) via a malformed DNS request.
