Detail

Unbound before 1.3.4 does not properly verify signatures for NSEC3 records, which allows remote attackers to cause secure delegations to be downgraded via DNS spoofing or other DNS-related attacks in conjunction with crafted delegation responses.

Title: DSA-1963-1 unbound -- cryptographic implementation error
Description: It was discovered that Unbound, a DNS resolver, does not properly check cryptographic signatures on NSEC3 records. As a result, zones signed with the NSEC3 variant of DNSSEC lose their cryptographic protection. The old stable distribution does not contain an unbound package. For the stable distribution, this problem has been fixed in version 1.0.2-1+lenny1. For the unstable distribution and the testing distribution, this problem has been fixed in version 1.3.4-1. We recommend that you upgrade your unbound package.

Id Description
58836 Unbound NSEC3 Record Signature Check Validation Bypass

Unbound contains a flaw that may allow a malicious user to bypass NSEC3 record signature checks. The issue is triggered when a malicious user sends a specially crafted delegation response in spoofed DNS packets. It is possible that the flaw may allow a secure delegation to be downgraded to insecure resulting in a loss of integrity.
