Detection & IOCsextracted from sources · hover to see the quote
- →Trigger point is an assertion failure in sexpr.c or alist.c when a malformed packet is sent to named's rndc control channel interface — monitor for named process crashes (assertion failures) originating from these source files. ↗
- →Authentication is NOT required to exploit this vulnerability — any connection to the rndc control channel port from an unauthenticated remote source should be treated as suspicious and alerted on. ↗
- →The exploit involves crafting an rndc request that sets an incorrect type value in the isccc_sexpr structure for the _auth or _ctrl records, causing isccc_alist_alistp() to return ISC_FALSE and triggering the REQUIRE assertion in isccc_alist_assq(). Inspect rndc packets for malformed or unexpected type fields in _auth/_ctrl records. ↗
- →The vulnerability is exploitable only when the rndc control channel is accessible — detect exposure by checking if named accepts remote rndc commands (i.e., a 'controls' statement is present in named.conf allowing non-localhost connections). ↗
- ·By default, named only allows rndc control channel connections from localhost (127.0.0.1 and ::1) if rndc.key exists; the attack surface is only exposed when a 'controls' statement explicitly permits remote connections. ↗
- ·Mitigation (not a fix) is to restrict the 'controls' statement in named.conf to trusted systems only; this limits exposure but does not patch the underlying assertion failure. ↗

Title: Bind vulnerabilities
Summary: Bind could be made to crash if it received specially crafted network
traffic.
It was discovered that Bind incorrectly handled input received by the rndc
control channel. A remote attacker could possibly use this issue to cause
Bind to crash, resulting in a denial of service. (CVE-2016-1285)
It was discovered that Bind incorrectly parsed resource record signatures
for DNAME resource records. A remote attacker could possibly use this issue
to cause Bind to crash, resulting in a denial of service. (CVE-2016-1286)
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2016-1285 bind: malformed packet sent to rndc can trigger assertion failure
The following flaw, reported by ISC, was found in BIND:
Testing by ISC has uncovered a defect in control channel input handling which can cause named to exit due to an assertion failure in sexpr.c or alist.c when a malformed packet is sent to named's control channel (the interface which allows named to be controlled using the 'rndc" server control utility).
This assertion occurs before authentication but after network-address-based access controls have been applied. Or in other words: an attacker does not need to have a key or other authentication, but does need to be within the address list specified in the "controls" statement in named.conf which enables the control channel. If no "controls" statement is p
