Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS : Bind vulnerabilities (USN-8293-1)

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8293-1 advisory. Vitaly Simonovich discovered that Bind could exhaust memory during GSS-API TKEY negotiation. A remote attacker could...

bind: BIND 9 server memory exhaustion during GSS-API TKEY negotiation

A flaw was found in BIND. A remote attacker can exploit this vulnerability by sending maliciously-constructed packets to BIND servers configured for TKEY-based authentication via GSS-API Generic Security Service Application Program Interface tokens. This can lead to excessive memory consumption,...

bind: BIND: Denial of Service via specially crafted DNS messages

A flaw was found in the bind component, specifically within the named daemon. This vulnerability allows a remote attacker to send specially crafted Domain Name System DNS messages. These messages, which use unusual classes or meta-classes, can trigger assertion failures in the named daemon when...

Security Bulletin: Vault Terraform Provider Incorrect Defaults for LDAP Auth Method, Resulting in Insecure Configuration and Potential Authentication Bypass

Summary Vault’s Terraform Provider incorrectly set the default denynullbind parameter for the LDAP auth method to false by default. If the underlying LDAP server allowed anonymous or unauthenticated binds, this could result in authentication bypass. This vulnerability, CVE-2025-13357, is fixed in...

CVE-2026-3039

A flaw was found in BIND. A remote attacker can exploit this vulnerability by sending maliciously-constructed packets to BIND servers configured for TKEY-based authentication via GSS-API Generic Security Service Application Program Interface tokens. This can lead to excessive memory consumption,...

CVE-2026-5947

A flaw was found in BIND. A remote attacker could exploit a race condition during SIG0 signature validation of an incoming DNS message. If the "recursive-clients" limit is reached and the message is discarded, a use-after-free vulnerability may occur. This could lead to undefined behavior and...

CVE-2026-3593

A flaw was found in the BIND Berkeley Internet Name Domain DNS-over-HTTPS implementation. A remote attacker could send specially crafted HTTP/2 traffic to a DNS-over-HTTPS endpoint, leading to a use-after-free vulnerability. This could trigger memory corruption, potentially allowing the attacker ...
