CVE-2022-37434

### Vulnerable Library - zlibv1.2.11

A massively spiffy yet delicately unobtrusive compression library.

Library home page: https://github.com/madler/zlib.git

Found in HEAD commit: 802457f036ab4eb3ba012bdede243dbbc52f72ec

Found in base branch: main

### Vulnerable Source Files (1)

/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).

Found in base branch: main

### Vulnerable Source Files (1)

/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.
