Study of Post Quantum Status of Widely Used Protocols

The advent of quantum computing poses significant threats to classical public-key cryptographic primitives such as RSA and elliptic-curve cryptography. As many critical network and security protocols depend on these primitives for key exchange and authentication, there is an urgent need to...

[SECURITY] Fedora 43 Update: bind-9.18.47-1.fc43

BIND Berkeley Internet Name Domain is an implementation of the DNS Domain Name System protocols. BIND includes a DNS server named, which resolves host names to IP addresses; a resolver library routines for applications to use when interfacing with DNS; and tools for verifying that the DNS server ...

Arbitrary Code Injection

froxlor/froxlor is vulnerable to Arbitrary Code Injection. The vulnerability is due to improper validation of DNS record content in the DomainZones.add endpoint, which allows an attacker to inject malicious directives into zone files and manipulate DNS configuration...

cryptography has incomplete DNS name constraint enforcement on peer names

Summary In versions of cryptography prior to 46.0.5, DNS name constraints were only validated against SANs within child certificates, and not the "peer name" presented during each validation. Consequently, cryptography would allow a peer named bar.example.com to validate against a wildcard leaf...

CVE-2026-31945

LibreChat (versions 0.8.2-rc2 to 0.8.2) is vulnerable to SSRF via DNS resolution in agent actions or MCP. The issue arises because prior fixes only added hostname validation and do not verify whether DNS results map to private IPs, allowing access to internal resources (e.g., internal RAG API or ...

Security Bulletin: Operator for IBM DataPower Gateway vulnerable to Denial of Service

Summary This vulnerability can allow an invalid DNS response to cause an operator crash. Vulnerability Details CVEID:CVE-2026-25518 DESCRIPTION: cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and...

BIT-NGINX-2026-28753 NGINX ngx_mail_proxy_module vulnerability

NGINX Plus and NGINX Open Source have a vulnerability in the ngxmailsmtpmodule module due to the improper handling of CRLF sequences in DNS responses. This allows an attacker-controlled DNS server to inject arbitrary headers into SMTP upstream requests, leading to potential request manipulation...

CVE-2026-3591

A flaw was found in BIND, specifically in the named server's handling of DNS queries signed with SIG0. A remote attacker could exploit this use-after-return vulnerability by sending a specially-crafted DNS request. This could cause an Access Control List ACL to improperly match an IP address,...

EUVD-2026-15406

If a BIND resolver is performing DNSSEC validation and encounters a maliciously crafted zone, the resolver may consume excessive CPU. Authoritative-only servers are generally unaffected, although there are circumstances where authoritative servers may make recursive queries see:...

ALPINE-CVE-2026-3591

A use-after-return vulnerability exists in the named server when handling DNS queries signed with SIG0. Using a specially-crafted DNS request, an attacker may be able to cause an ACL to improperly mismatch an IP address. In a default-allow ACL denying only specific IP addresses, this may lead to...
