CVE-2015-3294

Publication date 27 April 2015

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
