|
|
Affected versions of this crate would call `Vec::set_len` on an uninitialized
|
|
vector with user-provided type parameter, in an interface of the HDR image
|
|
format decoder. They would then also call other code that could panic before
|
|
initializing all instances.
|
|
|
|
This could run Drop implementations on uninitialized types, equivalent to
|
|
use-after-free, and allow an attacker arbitrary code execution.
|
|
|
|
Two different fixes were applied. It is possible to conserve the interface by
|
|
ensuring proper initialization before calling `Vec::set_len`. Drop is no longer
|
|
called in case of panic, though.
|
|
|
|
Starting from version `0.22`, a breaking change to the interface requires
|
|
callers to pre-allocate the output buffer and pass a mutable slice instead,
|
|
avoiding all unsafe code.
