Overview

Affected versions of this package are vulnerable to Out-of-Bounds Write in the f->vendor[i] = get8_packet(f); function. An attacker can trigger an out-of-bounds write and potentially execute arbitrary code by providing a crafted file. This is due to an integer overflow in setup_malloc where a sufficiently large value in the variable sz overflows with sz+7 and the negative value passes the maximum available memory buffer check.
