ALPINE-CVE-2026-19445
A remote, unauthenticated TLS client can make a server crash or call through a freed pointer if its snicallback assigns a different context to SSLSocket.context the documented way to select a certificate per server name and nothing else keeps the original ssl.SSLContext alive. Typical cases are...
Astra Linux – Vulnerability in mbedtls
In Trusted Firmware Mbed TLS 2.24.0, a side-channel vulnerability exists in the decoding of Base64 PEM files. This vulnerability allows system-level administrator attackers to obtain information about secret RSA keys through a controlled-channel and side-channel attack on software running in...

CVE-2026-16318 QUIC Transport Parameters Memory Leak During HelloRetryRequest in s2n-tls
The QUIC transport parameters extension handler in s2n-tls incorrectly uses s2nalloc instead of s2nrealloc to store the peer's transport parameters. When a TLS 1.3 connection goes through a HelloRetryRequest, the handler is called twice on the same connection. On the second call, s2nalloc zeroes...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building
A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...
curl: Trailing-dot IPv4 URL bypasses IP-address guard, allows wildcard DNS SAN match
Hi all, Sorry to ruin anybody's day, but we've discovered another issue when it comes to dots. We've found a TLS certificate verification bypass that lets a trailing-dot IPv4 URL -- https://127.0.0.1./ -- pass peer authentication against a wildcard DNS SAN certificate such as DNS:.0.0.1. The IP...
