Buffer Overflow Vulnerability in OpenSSL's asn1_d2i_read_bio Function

CVE-2012-2110 · HIGH Severity

AV:N/AC:L/AU:N/C:P/I:P/A:P

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.
