CVE-2012-2110
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.");
