CVE-2026-34513

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework for asyncio and Python. This vulnerability allows a remote attacker to cause excessive memory usage by exploiting an unbounded Domain Name System DNS cache. This can lead to a Denial of Service DoS condition, making the...

AIOHTTP Affected by Denial of Service (DoS) via Unbounded DNS Cache in TCPConnector

Summary An unbounded DNS cache could result in excessive memory usage possibly resulting in a DoS situation. Impact If an application makes requests to a very large number of hosts, this could cause the DNS cache to continue growing and slowly use excessive amounts of memory. ----- Patch:...

Insecure Default Initialization of Resource

Overview Affected versions of this package are vulnerable to Insecure Default Initialization of Resource due to DNS rebinding protection being disabled by default in HTTP-based servers using StreamableHTTPHandler or SSEHandler. An attacker can access internal resources or invoke tools exposed by...

SUSE CVE-2026-24028

An attacker might be able to trigger an out-of-bounds read by sending a crafted DNS response packet, when custom Lua code uses newDNSPacketOverlay to parse DNS packets. The out-of-bounds read might trigger a crash, leading to a denial of service, or access unrelated memory, leading to potential...

CVE-2026-34073

A flaw was found in the cryptography library. This vulnerability occurs because DNS Domain Name System name constraints were not properly validated against the "peer name" during certificate validation, only against Subject Alternative Names SANs within child certificates. This oversight could...

CVE-2026-24029

A flaw was found in dnsdist, a high-performance DNS Domain Name System load balancer. When the earlyacldrop option is disabled on a DNS over HTTPS DoH frontend, the Access Control List ACL check is bypassed. This allows any client to send DoH queries, potentially leading to unauthorized access to...

CVE-2026-24030

A flaw was found in DNSdist. A remote attacker could exploit this vulnerability by sending specially crafted DNS over QUIC Quick UDP Internet Connections or DNS over HTTP/3 Hypertext Transfer Protocol version 3 payloads. This could trick DNSdist into allocating excessive memory, leading to a deni...

EUVD-2026-17403

When the earlyacldrop earlyACLDrop in Lua option is disabled default is enabled on a DNS over HTTPs frontend using the nghttp2 provider, the ACL check is skipped, allowing all clients to send DoH queries regardless of the configured ACL...

EUVD-2026-17405

An attacker might be able to trick DNSdist into allocating too much memory while processing DNS over QUIC or DNS over HTTP/3 payloads, resulting in a denial of service. In setups with a large quantity of memory available this usually results in an exception and the QUIC connection is properly...

EUVD-2026-17407

An attacker might be able to trigger an out-of-bounds write by sending crafted DNS responses to a DNSdist using the DNSQuestion:changeName or DNSResponse:changeName methods in custom Lua code. In some cases the rewritten packet might become larger than the initial response and even exceed 65535...
