A vulnerability has been reported in ldns, which can be exploited by malicious people to compromise an application using the library.
The vulnerability is caused due to a boundary error in the "ldns_rr_new_frm_str_internal()" function in rr.c when handling the data of unknown RR types ("\#"). This can be exploited to cause a heap-based buffer overflow by e.g. processing specially crafted DNS Resource Records.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is reported in version 1.6.10. Other versions may also be affected.
Solution: Update to version 1.6.11.
Provided and/or discovered by: Reported by David Keeler in a bug report.
