Subject: [PATCH] Correct incorrect inputs provided to the CRC functions.
|
|
|
|
The previous releases of zlib were not sensitive to incorrect CRC
|
|
inputs with bits set above the low 32. This commit restores that
|
|
behavior, so that applications with such bugs will continue to
|
|
operate as before.
