libssh2: Fix of 2 CVEs

CVE-2019-13115: add bounds-checked stringbuf helpers and use them in diffiehellmansha1 to prevent out-of-bounds read on malformed KEX reply - CVE-2019-17498: harden bounds checks in SSHMSGDISCONNECT, SSHMSGDEBUG and SSHMSGGLOBALREQUEST handlers to prevent integer overflow / out-of-bounds read...

JLSEC-2026-466 Mbed TLS peer can force the FFDH shared secret into a small set of values

An issue was discovered in Mbed TLS 3.5.x and 3.6.x through 3.6.5 and TF-PSA-Crypto 1.0. There is a lack of contributory behavior in FFDH due to improper input validation. Using finite-field Diffie-Hellman, the other party can force the shared secret into a small set of values lack of contributor...

Issue summary: Checking excessively long DH keys or parameters may be very slow. Impact summary: Applications that use the functions DHcheck, DHcheckex or EVPPKEYparamcheck to check a DH key or DH parameters may experience long delays. Where the key or parameters that are being checked have been...

CVE-2026-41989

A flaw was found in Libgcrypt. A remote attacker could exploit this vulnerability by sending crafted Elliptic Curve Diffie-Hellman ECDH ciphertext to the gcrypkdecrypt function. This can lead to a heap-based buffer overflow, potentially causing a denial of service DoS condition. Mitigation...

rust-openssl: Deriver::derive and PkeyCtxRef::derive can overflow short buffers on OpenSSL 1.1.1

Deriver::derive and PkeyCtxRef::derive sets len = buf.len and passes it as the in/out length to EVPPKEYderive, relying on OpenSSL to honor it. On OpenSSL 1.1.x, X25519, X448, DH and HKDF-extract ignore the incoming keylen, unconditionally writing the full shared secret 32/56/prime-size bytes. A...
