New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 5.2

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

It was discovered that named did not invalidate previously cached RRSIG records when adding an NCACHE record for the same entry to the cache. A remote attacker allowed to send recursive DNS queries to named could use this flaw to crash named. (CVE-2010-3613)

A flaw was found in the DNSSEC validation code in named. If named had multiple trust anchors configured for a zone, a response to a request for a record in that zone with a bad signature could cause named to crash. (CVE-2010-3762)

It was discovered that, in certain cases, named did not properly perform DNSSEC validation of an NS RRset for zones in the middle of a DNSKEY algorithm rollover. This flaw could cause the validator to incorrectly determine that the zone is insecure and not protected by DNSSEC. (CVE-2010-3614)

After installing the update, the BIND daemon (named) will be restarted automatically.

Solution

Update the affected packages.
