The issue is caused by a heap-based buffer overflow in the ASN.1 decoder. This can be exploited by remote attackers using specially crafted OCTET STRING data, potentially leading to a denial of service or the execution of arbitrary code.

The issue allows user-assisted man-in-the-middle attackers to bypass intended access restrictions. This can be achieved by triggering a user dialog for an X.509 certificate problem, such as an expired certificate or a mismatched hostname for a domain with pinning enabled.
