CVE-2011-3581  (opens in a new tab)
CWE-119  (opens in a new tab)

How to fix?

Upgrade ldns to version 1.6.11 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds. Heap-based buffer overflow in the ldns_rr_new_frm_str_internal function in ldns before 1.6.11 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a Resource Record (RR) with an unknown type containing input that is longer than a specified length.
