CVE-2026-41677

CVE-2026-41677 affects the rust-openssl bindings for Rust. From 0.9.0 up to before 0.10.78, the *_from_pem_callback APIs did not validate the length returned by the user’s callback, allowing a password callback that returns more data than the destination buffer to cause an over-read in some OpenS...

CVE-2026-41677 rust-openssl: Out-of-bounds read in PEM password callback when user callback returns an oversized length

rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.9.0 to before 0.10.78, 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...

CVE-2026-41676 rust-openssl: Deriver::derive and PkeyCtxRef::derive can overflow short buffers on OpenSSL 1.1.1

rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.9.27 to before 0.10.78, 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-extra...

rust-openssl 缓冲区错误漏洞

rust-openssl is an open-source library in the rust ecosystem that allows for interaction with the OpenSSL library. In versions 0.9.0 to 0.10.78 of rust-openssl, there was a buffer error vulnerability. This vulnerability stemmed from the frompemcallback API not verifying the length returned by use...

rust-openssl 安全漏洞

rust-openssl is an open-source library designed for interacting with the OpenSSL library. There were security vulnerabilities in the version of rust-openssl from 0.9.27 to 0.10.78. These vulnerabilities stemmed from the use of Deriver::derive, where len = buf.len was set as the input/output lengt...

rust-openssl 缓冲区错误漏洞

rust-openssl is an open-source library in the rust ecosystem that allows for interaction with the OpenSSL library. Prior to version 0.10.78, rust-openssl had a buffer error vulnerability. This vulnerability stemmed from an incorrect assertion in aes::unwrapkey, where the condition out.len + 8 =...

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...

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...
