kernel: keys: Fix linking a duplicate key to a keyring's assoc_array
A race condition was found in the Linux kernel's keyring subsystem. When concurrent DNS queries resolve the same hostname, a duplicate index key can be created in the keyring's assocarray. The assocarray implementation has a BUGON check that detects this invalid state, causing a kernel crash. Thi...
OESA-2024-1489 systemd security update
systemd is a system and service manager that runs as PID 1 and starts the rest of the system. Security Fixes: Certain DNSSEC aspects of the DNS protocol in RFC 4033, 4034, 4035, 6840, and related RFCs allow remote attackers to cause a denial of service CPU consumption via one or more DNSSEC...
coredns 安全漏洞
CoreDNS is a DNS server for the CoreDNS community. A security vulnerability exists in coredns that stems from an incorrect cache implementation; this issue could result in invalid cache entries being returned...
OpenJDK: HTTP/2 client improper reverse DNS lookup (8315708)
A flaw was found in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE component: Networking. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle...
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...
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: 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...
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...

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...

UBUNTU-CVE-2023-29483
eventlet before 0.35.2, as used in dnspython before 2.6.0, allows remote attackers to interfere with DNS name resolution by quickly sending an invalid packet from the expected IP address and source port, aka a "TuDoor" attack. In other words, dnspython does not have the preferred behavior in whic...
