It was discovered that there was an issue in the Go programming language library where an attacker could generate a MIME request such that the server ran out of file descriptors.

For Debian 7 ‘Wheezy’, this issue has been fixed in golang version 2:1.0.2-1.1+deb7u1.

We recommend that you upgrade your golang 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.
