CVE-2025-66199

Issue summary: A TLS 1.3 connection using certificate compression can be forced to allocate a large buffer before decompression without checking against the configured certificate size limit. Impact summary: An attacker can cause per-connection memory allocations of up to approximately 22 MiB and...

CVE-2025-66199

OpenSSL versions 3.6, 3.5, 3.4, and 3.3 are vulnerable to a Denial of Service (DoS) condition during TLS 1.3 connections using certificate compression. The root cause is an unbounded heap buffer allocation where the peer-supplied uncompressed certificate length from a CompressedCertificate messag...

CVE-2025-15469

The openssl dgst command-line tool in OpenSSL 3.5 and 3.6 is vulnerable to a silent truncation issue. When using one-shot signing algorithms—specifically Ed25519 , Ed448 , and ML-DSA (variants 44, 65, and 87)—the tool buffers input with a 16MB limit. If the input exceeds this size, the tool silen...
