Overview

Affected versions of this package are vulnerable to Out-of-bounds Write in the parsing process of DHAV file headers due to an integer underflow in offset calculation, which allows reading memory before the start of the allocated buffer. An attacker can cause out-of-bounds memory reads by supplying a specially crafted DHAV file with manipulated offsets.
