HTTP: zlib Library inflateGetHeader Handling Buffer Overflow
This signature detects attempts to exploit a known vulnerability against zlib Library inflateGetHeader. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of thezlib Library.
Extended Description
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).
