CVE-2026-114605 dnspython dns.name.from_wire_parser() excessive CPU use

dnspython is a DNS toolkit for Python. Prior to 2.9.0, dns.name.fromwireparser follows attacker-controlled DNS compression pointer chains without a hop limit. A malicious DNS wire-format message can force excessive pointer traversal during name decompression, causing high CPU use, application...

CVE-2026-114605

The dnspython DNS toolkit for Python is vulnerable to excessive CPU use in versions prior to 2.9.0 . The root cause is located in dns.name.from_wire_parser(), which follows attacker-controlled DNS compression pointer chains without a hop limit. A malicious DNS wire-format message can trigger exce...

DEBIAN-CVE-2026-96405

NLnet Labs Unbound up to and including version 1.26.1 limits compression-pointer traversal for each individual domain-name operation but has no aggregate inbound decompression-work budget. Many chained compression pointers in a message results in a lot of CPU usage following them. A malicious act...

Linux Distros Unpatched Vulnerability : CVE-2026-96405

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - NLnet Labs Unbound up to and including version 1.26.1 limits compression-pointer traversal for each individual domain-name operation but has no aggregate inboun...

NLnet Labs Unbound Resource Management Vulnerability

NLnet Labs Unbound versions 1.26.1 and earlier have a resource management vulnerability. This vulnerability stems from the lack of a overall budget limit on the incoming decompression workload. A large number of chained compression pointers can lead to excessive CPU usage. Attackers can exploit...

CVE-2026-69184 c-ares: CPU-exhaustion denial of service via unbounded DNS name compression pointer chains

c-ares is an asynchronous resolver library. Prior to 1.34.7, aresdnsnameparse enforces backward DNS compression pointers but does not bound the total pointer hops or assembled name length. A malicious DNS server can send a response containing a long descending pointer chain and many resource...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the aresdnsnameparse function due to a lack of limits on the total pointer hops or assembled name length when processing DNS compression pointers. An attacker can cause excessive C...
