bind9: Querying RFC 1918 reverse zones may cause an assertion failure when “nxdomain-redirect” is enabled

A flaw was found in the bind package which may result in a Denial of Service in named process. This is a result of a reachable assertion, leading named to prematurely terminate when both conditions are met: nxdomain-redirect for the queried domain is configured and the resolver receives a PTR...

Important: Red Hat Security Advisory: bind security update

An update for bind is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from the...

bind9: Enabling both DNS64 and serve-stale may cause an assertion failure during recursive resolution

A flaw was found in the bind package. This issue may allow an attacker to query in a DNS64 enabled resolver node with a domain name triggering a server-stale data, triggering a code assertion, and resulting in a crash of named processes. This can allow a remote unauthenticated user to cause a...

bind9: Parsing large DNS messages may cause excessive CPU load

A flaw was found in the bind package. This issue may allow a remote attacker with no specific privileges to craft a specially long DNS message leading to an excessive and uncontrolled CPU usage, the server being unavailable, and a Denial of Service...

bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator

Processing specially crafted responses coming from DNSSEC-signed zones can lead to uncontrolled CPU usage, leading to a Denial of Service in the DNSSEC-validating resolver side. This vulnerability applies only for systems where DNSSEC validation is enabled...

Important: Red Hat Security Advisory: bind9.16 security update

An update for bind9.16 is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Important.

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

A flaw was found in the named application, part of the bind9 package, which uses a cache database to speeds up DNS queries. To maintain its efficiency when running as a recursive name resolver, named performs a cache database clean up under certain conditions. This issue may allow an attacker to...

bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources

A flaw was found in bind9. By flooding a DNSSEC resolver with responses coming from a DNSEC-signed zone using NSEC3, an attacker can lead the targeted resolver to a CPU exhaustion, further leading to a Denial of Service on the targeted host. This vulnerability applies only for systems where DNSSE...

nodejs: code injection and privilege escalation through Linux capabilities

A flaw was found in Node.js. On Linux, Node.js ignores certain environment variables if an unprivileged user has set them while the process is running with elevated privileges, except for CAPNETBINDSERVICE. Due to a bug in the implementation of this exception, Node.js incorrectly applies this...
