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...

rust-opennssl has an Out-of-bounds read in PEM password callback when returning an oversized length

The frompemcallback APIs did not validate the length returned by the user's callback. A password callback that returns a value larger than the buffer it was given can cause some versions of OpenSSL to over-read this buffer. OpenSSL 3.x is not affected by this...

GHSA-8C75-8MHR-P7R9 rust-openssl has incorrect bounds assertion in aes key wrap

Summary aes::unwrapkey has an incorrect bounds assertion on the out buffer size, which can lead to out-of-bounds write. Details aes::unwrapkey contains an incorrect assertion: it checks that out.len + 8 = in.len - 8, ensuring the output buffer is large enough. Because of the inverted check, the...

GHSA-GHM9-CR32-G9QJ rust-openssl: rustMdCtxRef::digest_final() writes past caller buffer with no length check

EVPDigestFinal always writes EVPMDCTXsizectx to the out buffer. If out is smaller than that, MdCtxRef::digestfinal writes past its end, usually corrupting the stack. This is reachable from safe Rust...

rust-openssl: Unchecked callback length in PSK/cookie trampolines leaks adjacent memory to peer

The FFI trampolines behind SslContextBuilder::setpskclientcallback, setpskservercallback, setcookiegeneratecb, and setstatelesscookiegeneratecb forwarded the user closure's returned usize directly to OpenSSL without checking it against the &mut u8 that was handed to the closure. This can lead to...

Siemens RUGGEDCOM, SCALANCE and SIMATIC Out-of-bounds Read (CVE-2021-3712)

ASN.1 strings are represented internally within OpenSSL as an ASN1STRING structure which contains a buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings which are repesented as a buffer for the string data which is terminated with a NUL 0 byte...
