Vulnerability Details

Zlib in versions v0.8 to v1.2.11 is vulnerable to use-of-uninitialized-value in inflate.
There are a couple of places in inflate() where UPDATE is called with state->check as its first parameter, without a guarantee that this value has been initialized (state comes from a ZALLOC in inflateInit). This causes use of uninitialized check value.
