Debian DLA-1255-1 : bind9 security update

high Nessus Plugin ID 106211

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Jayachandran Palanisamy of Cygate AB reported that BIND, a DNS server implementation, was improperly sequencing cleanup operations, leading in some cases to a use-after-free error, triggering an assertion failure and crash in named.

For Debian 7 'Wheezy', these problems have been fixed in version 1:9.8.4.dfsg.P1-6+nmu2+deb7u19.

We recommend that you upgrade your bind9 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.

Solution

Upgrade the affected packages.
