Ubuntu 10.04 LTS / 11.10 / 12.04 LTS / 12.10 : bind9 vulnerability (USN-1783-1)

high Nessus Plugin ID 65763

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Matthew Horsfall discovered that Bind incorrectly handled regular expression checking. A remote attacker could use this flaw to cause Bind to consume an excessive amount of memory, possibly resulting in a denial of service. This issue was corrected by disabling RDATA regular expression syntax checking.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
