/vendor/zlib-1.2.11.1/inflate.c

Vulnerability Details

zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference).

/vendor/zlib-1.2.11.1/inflate.c

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.
