Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow due to improper restriction of operations within the bounds of a memory buffer in the inftree9.c endpoint. An attacker can achieve heap corruption or execute arbitrary code by supplying specially crafted input data.
Note: This issue is related to CVE-2016-9840 in zlib. The vulnerable logic in inftree9.c is derived from the same codebase and reflects the same underlying flaw.
