bind: Cache poisoning attacks with unsolicited RRs

A vulnerability exists in BIND’s DNS resolver logic that makes it overly permissive when accepting resource records RRs in responses. Under certain conditions, this flaw allows attackers to inject unsolicited or forged DNS records into the cache. This can be exploited to poison the resolver cache...

bind: Resource exhaustion via malformed DNSKEY handling

A vulnerability was found in BIND 9 resolvers, where processing malformed DNSKEY records from a specially crafted zone can lead to resource exhaustion, primarily causing excessive CPU utilization. This issue enables a remote, unauthenticated attacker to degrade resolver performance and potentiall...

bind: Cache poisoning due to weak PRNG

A vulnerability was found in BIND resolvers caused by a weakness in the Pseudo Random Number Generator PRNG. This weakness allows an attacker to potentially predict the source port and query ID used by BIND, enabling cache poisoning attacks. If successful, the attacker can inject malicious DNS...

DEBIAN-CVE-2023-2911

If the recursive-clients quota is reached on a BIND 9 resolver configured with both stale-answer-enable yes; and stale-answer-client-timeout 0;, a sequence of serve-stale-related lookups could cause named to loop and terminate unexpectedly due to a stack overflow. This issue affects BIND 9 versio...

SUSE CVE-2002-1146

The BIND 4 and BIND 8.2.x stub resolver libraries, and other libraries such as glibc 2.2.5 and earlier, libc, and libresolv, use the maximum buffer size instead of the actual size when processing a DNS response, which causes the stub resolvers to read past the actual boundary "read buffer...

SUSE CVE-2018-5745

"managed-keys" is a feature which allows a BIND resolver to automatically maintain the keys used by trust anchors which operators configure for use in DNSSEC validation. Due to an error in the managed-keys feature it is possible for a BIND server which uses managed-keys to exit due to an assertio...

SUSE CVE-2022-3924

This issue can affect BIND 9 resolvers with stale-answer-enable yes; that also make use of the option stale-answer-client-timeout, configured with a value greater than zero. If the resolver receives many queries that require recursion, there will be a corresponding increase in the number of clien...

Amazon Linux AMI : bind (ALAS-2018-954)

Improper fetch cleanup sequencing in the resolver can cause named to crash : A use-after-free flaw leading to denial of service was found in the way BIND internally handled cleanup operations on upstream recursion fetch contexts. A remote attacker could potentially use this flaw to make named,...

bind: Processing a response containing CNAME or DNAME with unusual order can crash resolver

A denial of service flaw was found in the way BIND handled a query response containing CNAME or DNAME resource records in an unusual order. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response...

bind: deleted domain name resolving flaw

The resolver in ISC BIND 9 through 9.8.1-P1 overwrites cached server names and TTL values in NS records during the processing of a response to an A record query, which allows remote attackers to trigger continued resolvability of revoked domain names via a "ghost domain names" attack...
