Description

In connman, stack-based buffer overflow in 'dnsproxy.c' allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted response query string passed to the 'name' variable.

For Debian 7 'Wheezy', these problems have been fixed in version 1.0-1.1+wheezy2.

We recommend that you upgrade your connman packages.

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.
