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:...

Use-After-Free

github.com/envoyproxy/envoy is vulnerable to a Use-After-Free. The vulnerability is due to improper handling of DNS cache operations in the Dynamic Forward Proxy implementation, where a completion callback can trigger new or remove existing DNS resolutions, which allows an attacker to cause...

CVE-2025-59781 BIG-IP DNS cache vulnerability

When DNS cache is configured on a BIG-IP or BIG-IP Next CNF virtual server, undisclosed DNS queries can cause an increase in memory resource utilization. Note: Software versions which have reached End of Technical Support EoTS are not evaluated...

SUSE CVE-2005-0877

Dnsmasq before 2.21 allows remote attackers to poison the DNS cache via answers to queries that were not made by Dnsmasq...

SUSE CVE-2010-4448

Unspecified vulnerability in the Java Runtime Environment JRE in Oracle Java SE and Java for Business 6 Update 23 and earlier, 5.0 Update 27 and earlier, and 1.4.229 earlier allows remote untrusted Java Web Start applications and untrusted Java applets to affect integrity via unknown vectors...

A flaw was found in dnsmasq in versions before 2.85. When configured to use a specific server for a given network interface dnsmasq uses a fixed port while forwarding queries. An attacker on the network able to find the outgoing port used by dnsmasq only needs to guess the random transmission ID to forge a reply and get it accepted by dnsmasq. This flaw makes a DNS Cache Poisoning attack much easier. The highest threat from this vulnerability is to data integrity.
