A flaw was found in wv. When parsing a Microsoft Word document containing malformed stylesheet data, the library fails to properly validate style indexes, leading to a heap-based out-of-bounds read. An attacker could exploit this vulnerability by enticing a user or automated service to open a specially crafted document, causing the application to crash and resulting in a Denial of Service (DoS).
