CRITICAL9.8EPSS 0.06%rust-openssl: rustMdCtxRef::digest_final() writes past caller buffer with no length check
發布日:2026/4/22修改日:2026/6/2
也稱為:DEBIAN-CVE-2026-41681
描述
rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.10.39 to before 0.10.78, EVP_DigestFinal() always writes EVP_MD_CTX_size(ctx) to the out buffer. If out is smaller than that, MdCtxRef::digest_final() writes past its end, usually corrupting the stack. This is reachable from safe Rust. This vulnerability is fixed in 0.10.78.
