DescriptionNVD
The *_from_pem_callback 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.
AnalysisAI
Buffer over-read in rust-openssl's password callback APIs allows information disclosure when a user-supplied callback returns a value larger than the provided buffer. The vulnerability affects rust-openssl bindings to OpenSSL 1.x and 2.x; OpenSSL 3.x implementations are not vulnerable. …
