CVE-2018-5734 A malformed request can trigger an assertion failure in badcache.c

While handling a particular type of malformed packet BIND erroneously selects a SERVFAIL rcode instead of a FORMERR rcode. If the receiving view has the SERVFAIL cache feature enabled, this can trigger an assertion failure in badcache.c when the request doesn't contain all of the expected...

CVE-2018-5737

CVE-2018-5737 concerns ISC BIND 9.12.x. The issue arises from the implementation of the new serve-stale feature, which can trigger an assertion failure in rbtdb.c even when stale-answer-enable is off. Additionally, interaction between serve-stale and NSEC aggressive negative caching can, in some ...

CVE-2018-5734

The CVE-2018-5734 issue concerns ISC BIND where handling a malformed DNS request causes an assertion failure in badcache.c due to selecting SERVFAIL instead of FORMERR. Affected versions are BIND 9.10.5-S1 to 9.10.5-S4 and 9.10.6-S1/S2. The connected documents describe the root cause as an incorr...

CVE-2016-9778

CVE-2016-9778 affects ISC BIND and is triggered by handling specific queries when using the nxdomain-redirect feature in certain BIND versions (9.9.8-S1 to 9.9.8-S3, 9.9.9-S1 to 9.9.9-S6, 9.11.0-9.11.0-P1). The vulnerability can cause a REQUIRE assertion failure in db.c, potentially crashing or s...

CVE-2018-5736

CVE-2018-5736 is an ISC BIND vulnerability affecting versions 9.12.0 and 9.12.1. The issue is an error in the zone database reference counting that can trigger an assertion failure when a vulnerable server performs several slave-zone transfers in quick succession (for example after valid NOTIFY m...

CVE-2017-3145

CVE-2017-3145 affects BIND: the resolver incorrectly sequenced cleanup operations on upstream recursion fetch contexts, causing a use-after-free that can trigger an assertion failure and crash named. Affected versions include BIND 9.0.0 through 9.8.x, 9.9.0–9.9.11, 9.10.0–9.10.6, 9.11.0–9.11.2, 9...

CVE-2017-3136 An error handling synthesized records could cause an assertion failure when using DNS64 with "break-dnssec yes;"

A query with a specific set of characteristics could cause a server using DNS64 to encounter an assertion failure and terminate. An attacker could deliberately construct a query, enabling denial-of-service against a server if it was configured to use the DNS64 feature and other preconditions were...

CVE-2018-5740 A flaw in the "deny-answer-aliases" feature can cause an assertion failure in named

"deny-answer-aliases" is a little-used feature intended to help recursive server operators protect end users against DNS rebinding attacks, a potential method of circumventing the security model used by client browsers. However, a defect in this feature makes it easy, when the feature is in use, ...

CVE-2017-3137

CVE-2017-3137 is a denial-of-service issue in BIND where a response containing CNAME or DNAME records can cause named to exit with an assertion failure when records are in an unusual order. Affected upstream releases include multiple 9.x series (e.g., 9.9.9-P6 through 9.11.1rc1, 9.9.9-S8; also li...

CVE-2018-5737 BIND 9.12's serve-stale implementation can cause an assertion failure in rbtdb.c or other undesirable behavior, even if serve-stale is not enabled.

A problem with the implementation of the new serve-stale feature in BIND 9.12 can lead to an assertion failure in rbtdb.c, even when stale-answer-enable is off. Additionally, problematic interaction between the serve-stale feature and NSEC aggressive negative caching can in some cases cause...

CVE-2018-5736

An error in zone database reference counting can lead to an assertion failure if a server which is running an affected version of BIND attempts several transfers of a slave zone in quick succession. This defect could be deliberately exercised by an attacker who is permitted to cause a vulnerable...

CVE-2018-5740

CVE-2018-5740 is a flaw in the deny-answer-aliases feature of BIND that can cause an assertion failure in named, potentially restarting the bind process (denial of service). Affected BIND versions include 9.7.0–9.8.8, 9.9.0–9.9.13, 9.10.0–9.10.8, 9.11.0–9.11.4, 9.12.0–9.12.2, and 9.13.0–9.13.2. R...

CVE-2017-3145 Improper fetch cleanup sequencing in the resolver can cause named to crash

BIND was improperly sequencing cleanup operations on upstream recursion fetch contexts, leading in some cases to a use-after-free error that can trigger an assertion failure and crash in named. Affects BIND 9.0.0 to 9.8.x, 9.9.0 to 9.9.11, 9.10.0 to 9.10.6, 9.11.0 to 9.11.2, 9.9.3-S1 to 9.9.11-S1...

CVE-2017-3135

Under some conditions when using both DNS64 and RPZ to rewrite query responses, query processing can resume in an inconsistent state leading to either an INSIST assertion failure or an attempt to read through a NULL pointer. Affects BIND 9.8.8, 9.9.3-S1 - 9.9.9-S7, 9.9.3 - 9.9.9-P5, 9.9.10b1,...
