## Description

The asn1\_d2i\_read\_bio function in crypto/asn1/a\_d2i\_fp.c in OpenSSL before
0.9.8v, 1.0.0 before 1.0.0i, and 1.0.1 before 1.0.1a does not properly
interpret integer data, which allows remote attackers to conduct buffer
overflow attacks, and cause a denial of service (memory corruption) or
possibly have unspecified other impact, via crafted DER data, as
demonstrated by an X.509 certificate or an RSA public key.
