unbound: Unbound Cache poisoning

A cache poisoning flaw was found in Unbound. Resolvers supporting EDNS Client Subnet ECS must segregate outgoing queries to accommodate different outgoing ECS information. This issue reopens resolvers to a birthday paradox attack, known as the Rebirthday Attack, which attempts to match the DNS...

CVE-2025-5994 Cache poisoning via the ECS-enabled Rebirthday Attack

A multi-vendor cache poisoning vulnerability named 'Rebirthday Attack' has been discovered in caching resolvers that support EDNS Client Subnet ECS. Unbound is also vulnerable when compiled with ECS support, i.e., '--enable-subnet', AND configured to send ECS information along with queries to...

CVE-2025-5994

CVE-2025-5994 describes a rebirthday cache-poisoning risk in ECS-enabled caching resolvers. Affected product: Unbound (if built with ECS support and configured to send ECS data upstream). Root cause: need to segregate outgoing queries by ECS info; otherwise an attacker could exploit DNS transacti...

uClibc, uClibc-ng libraries have monotonically increasing DNS transaction ID

Overview The uClibc and uClibc-ng libraries, prior to uClibc-ng 1.0.41, are vulnerable to DNS cache poisoning due to the use of predicatble DNS transaction IDs when making DNS requests. This vulnerability can allow an attacker to perform DNS cache poisoning attacks against a vulnerable environmen...
