NVD Description

Note: Versions mentioned in the description apply only to the upstream ldns-python package and not the ldns-python package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

When ldns version 1.7.1 verifies a zone file, the ldns_rr_new_frm_str_internal function has a heap out of bounds read vulnerability. An attacker can leak information on the heap by constructing a zone file payload.
