CVE-2011-4869

Publication date 20 December 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

validator/val_nsec3.c in Unbound before 1.4.13p2 does not properly perform proof processing for NSEC3-signed zones, which allows remote DNS servers to cause a denial of service (daemon crash) via a malformed response that lacks expected NSEC3 records, a different vulnerability than CVE-2011-4528.
