Read on uninitialized buffer in postscript
Affected versions of this crate passes an uninitialized buffer to a user-provided Read implementation.
Arbitrary Read implementations can read from the uninitialized buffer (memory exposure) and also can return incorrect number of bytes written to the buffer. Reading from uninitialized memory produces undefined values that can quickly invoke undefined behavior.
This flaw was fixed in commit 8026286 by zero-initializing the buffer before handing to a user-provided Read.

An issue was discovered in the postscript crate before 0.14.0 for Rust. It might allow attackers to obtain sensitive information from uninitialized memory locations via a user-provided Read implementation.
