WS-2021-0057
Date: January 31, 2021
An issue was discovered in "outer_cgi" before v0.2.1. The "KeyValueReader" type in affected versions of this crate set up an uninitialized memory buffer and passed them to be read in to a user-provided "Read" instance. The "Read" instance could read uninitialized memory and cause undefined behavior and miscompilations. This issue was fixed in commit dd59b30 by zero-initializing the buffers before passing them.
