Red Hat Bugzilla – Bug 1259085
CVE-2015-5986 Bind: fromwire_openpgpkey() incorrect boundary check Denial of Service
Last modified: 2015-09-24 04:26:17 EDT
The following flaw, reported by ISC, was found in recent versions of BIND 9 ( 9.9.7 through 9.9.7-P2, and 9.10.2 through 9.10.2-P3):
An incorrect boundary check in openpgpkey_61.c can cause named to
terminate due to a REQUIRE assertion failure. This defect can be
deliberately exploited by an attacker who can provide a maliciously
constructed response in answer to a query.
Red Hat would like to thank ISC for reporting this issue.
