MemBio::get_buf has undefined behavior with empty buffers

Details
Package openssl
Version 0.10.63
URL sfackler/rust-openssl#2266
Date 2024-07-21
Patched versions >=0.10.66

Previously, MemBio::get_buf called slice::from_raw_parts with a null-pointer, which violates the functions invariants, leading to undefined behavior. In debug builds this would produce an assertion failure. This is now fixed.

See advisory page for additional details.
