CVE-2023-50868 [HIGH] Bind vulnerabilities Title: Bind vulnerabilities Summary: Several security issues were fixed in Bind. Shoham Danino, Anat Bremler-Barr, Yehuda Afek, and Yuval Shavitt discovered that Bind incorrectly handled parsing large DNS messages. A remote attacker could possibly use this issue to cause Bind to consume resources, leading to a denial of service. (CVE-2023-4408) Elias Heftrig, Haya Schulmann, Niklas Vogel, and Michael Waidner discovered that Bind icorrectly handled validating DNSSEC messages. A remote attacker could possibly use this issue to cause Bind to consume resources, leading to a denial of service. (CVE-2023-50387) It was discovered that Bind incorrectly handled preparing an NSEC3 closest encloser proof.

bind9: Specific recursive query patterns may lead to an out-of-memory condition

CVE-2023-6516 [HIGH] CWE-400 bind9: Specific recursive query patterns may lead to an out-of-memory condition bind9: Specific recursive query patterns may lead to an out-of-memory condition To keep its cache database efficient, `named` running as a recursive resolver occasionally attempts to clean up the database. It uses several methods, including some that are asynchronous: a small chunk of memory pointing to the cache element that can be cleaned up is first allocated and then queued for later processing. It was discovered that if the resolver is continuously processing query patterns triggering this type of cache-database maintenance, `named` may not be able to handle the cleanup events in a timely manner. This in turn enables the list of queued cleanup events to grow infinitely large over time, allowing the configured `max-cache-size` limit to be significantly exceeded. This issue affects BIN

CVE-2023-6516 [HIGH] CWE-770 Specific recursive query patterns may lead to an out-of-memory condition Specific recursive query patterns may lead to an out-of-memory condition FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability? One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this. Mariner: Mariner isc: isc Customer Action Required: Yes Remediation: CBL-Mariner Releases Reference:
