BIT-GOLANG-2026-32283 Unauthenticated TLS 1.3 KeyUpdate record can cause persistent connection retention and DoS in crypto/tls

If one side of the TLS connection sends multiple key update messages post-handshake in a single record, the connection can deadlock, causing uncontrolled consumption of resources. This can lead to a denial of service. This only affects TLS 1.3...

perl: CPAN.pm does not verify TLS certificates when downloading distributions over HTTPS

A flaw was found in Perl's CPAN, which doesn't check TLS certificates when downloading content. This happens due to verifySSL missing when suing the HTTP::Tiny library during the connection. This may allow an attacker to inject into the network path and perform a Man-In-The-Middle attack, causing...

http-tiny: perl: insecure TLS cert default

A vulnerability was found in Tiny, where a Perl core module and standalone CPAN package, does not verify TLS certificates by default. Users need to explicitly enable certificate verification with the verifySSL=1 flag to ensure secure HTTPS connections. This oversight can potentially expose...

CVE-2026-39304

A flaw was found in Apache ActiveMQ Client, Apache ActiveMQ Broker, and Apache ActiveMQ. A remote attacker can exploit this vulnerability by rapidly triggering Transport Layer Security TLS version 1.3 handshake KeyUpdates. This improper handling of KeyUpdates causes the broker to exhaust its memo...

LXD: Update of type field in restricted TLS certificate allows privilege escalation to cluster admin

Summary A restricted TLS certificate user can escalate to cluster admin by changing their certificate type from client to server via PUT/PATCH to /1.0/certificates/fingerprint. The non-admin guard and reset block in doCertificateUpdate fail to validate or reset the Type field, allowing a...

Apache Log4j Core: `verifyHostName` attribute silently ignored in TLS configuration

The fix for CVE-2025-68161 was incomplete: it addressed hostname verification only when enabled via the log4j2.sslVerifyHostName system property, but not when configured through the verifyHostName attribute of the element. Although the verifyHostName configuration attribute was introduced in Log4...

nodejs: Nodejs denial of service

A flaw in Node.js TLS error handling allows remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback are in use. Synchronous exceptions thrown during these callbacks bypass standard TLS error handling paths tlsClientError and error, causing either immediate...

crypto/tls: go crypto/tls ALPN negotiation error contains attacker controlled information

The crypto/tls conn.Handshake method returns an error on the server-side when ALPN negotation fails which can contain arbitrary attacker controlled information provided by the client-side of the connection which is not escaped. This affects programs which log these errors without any additional...

crypto/tls: Handshake messages may be processed at the incorrect encryption level in crypto/tls

A TLS connection handling flaw has been discovered in the golang crypto/tls library. During the TLS 1.3 handshake if multiple messages are sent in records that span encryption level boundaries for instance the Client Hello and Encrypted Extensions messages, the subsequent messages may be processe...

crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

crypto/tls: crypto/tls: Incorrect certificate validation during TLS session resumption

A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security TLS session resumption when certificate authority CA settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing ...
