ISC BIND deny-answer-aliases Assertion Failure Denial of Service (CVE-2018-5740)

A denial-of-service vulnerability has been reported in ISC BIND9. The vulnerability is due to improper handling of certain responses when BIND is configured to use the deny-answer-aliases feature. A remote attacker could exploit this vulnerability by providing a specific response to a DNAME or AN...

ISC BIND Assertion Failure Vulnerability (DoS)

According to its self-reported version, the instance of ISC BIND 9 running on the remote name server is 9.12.0 or 9.12.1. It is, therefore, affected by an assertion failure vulnerability which exists in the rbtdb.c due to the implementation of the new serve-stale feature and NSEC aggressive...

ISC BIND Assertion Failure Vulnerability

It is, therefore, affected by an assertion failure vulnerability which exists in badcache.c due to selecting a SERVFAIL rcode instead of a FORMER...

ISC BIND Allow-Recursion Vulnerability

According to its self-reported version, the instance of ISC BIND 9 running on the remote name server is 9.9.12, 9.10.7, 9.11.3, 9.12.0 prior to or equal to 9.12.1-P2, development release 9.13.0, 9.9.12-S1, 9.11.3-S1, or 9.11.3-S2. It is, therefore, affected by an allow-recursion vulnerability whi...

ISC BIND Assertion Failure Vulnerability (DoS)

According to its self-reported version, the instance of ISC BIND 9 running on the remote name server is 9.12.0 or 9.12.1. It is, therefore, affected by an assertion failure vulnerability which exists in the zone database reference counting mechanism due to attempting several transfers of a slave...
