Created ldns tracking bugs for this issue Affects: fedora-all [bug 741025] Affects: epel-all [bug 741026] This has been assigned the name CVE-2011-3581 Updates are now in all the testing repos (In reply to comment #3) > Updates are now in all the testing repos Brilliant, thanks Paul. The following ldns package updates has been pushed to testing repositories to correct this flaw: 1) ldns-1.6.11-2.fc16, 2) ldns-1.6.11-2.fc15, 3) ldns-1.6.11-2.fc14, 4) ldns-1.6.11-2.el6, 5) ldns-1.6.11-2.el5. Once they have passed the required amount of testing, they will be pushed to particular -stable repository. These have made it to stable a long time ago |
It was reported [1],[2] that the ldns_rr_new_frm_str_internal() function of ldns, when parsing data of unknown RR types ("\#"), suffered from a boundary error. This could be exploited to cause a heap-based buffer overflow by parsing specially crafted DNS Resource Records, possibly leading to the execution of arbitrary code. A fix [3] has been committed to ldns trunk.
