Name of the Vulnerable Software and Affected Versions
rust-openssl versions 0.9.27 through 0.10.77
Description
An issue exists where
Deriver::derive() and PkeyCtxRef::derive() set the len variable to buf.len() and pass it as the in/out length to EVP PKEY derive. When using OpenSSL 1.1.x, the X25519, X448, DH, and HKDF-extract algorithms ignore the incoming *keylen and unconditionally write the full shared secret. This can result in a heap or stack overflow if a caller passes a short slice.Recommendations
Update to version 0.10.78.
As a temporary workaround, restrict the use of
Deriver::derive() and PkeyCtxRef::derive() when integrated with OpenSSL 1.1.x.Exploit
Fix
DoS
Memory Corruption
