CVE-2021-25905

An issue was discovered in the bra crate before 0.1.1 for Rust. It lacks soundness because it can read uninitialized memory.

An issue was discovered in the bra crate before 0.1.1 for Rust. It lacks soundness because it can read uninitialized memory.

Affected versions of this crate creates an uninitialized buffer and passes it to user-provided `Read` implementation. This is unsound, because it allows safe Rust code to exhibit an undefined behavior (read from uninitialized memory). The flaw was corrected in version 0.1.1 by zero-initializing a newly allocated buffer before handing it to a user-provided `Read` implementation.

Buffered Random Access (BRA) provides easy random memory access to a sequential source of data in Rust. This is achieved by greedily retaining all memory read from a given source.
