| Detailed Description |
According to its banner, the remote web server is running a version of OpenSSL 1.0.0 is earlier than 1.0.0i. As such, the OpenSSL library itself is reportedly affected by a memory corruption vulnerability via an integer truncation error in the function 'asn1_d2i_read_bio' when reading ASN.1 DER format data.
Applications using the 'BIO' or 'FILE' based functions (i.e., 'd2i_*_bio' or 'd2i_*_fp' functions) are affected by this issue. Also affected are 'S/MIME' or 'CMS' applications using 'SMIME_read_PKCS7' or 'SMIME_read_CMS' parsers. The OpenSSL command line utility is affected if used to handle untrusted DER formatted
data.
Note that the SSL/TLS code of OpenSSL is not affected. Also not affected are applications using memory-based ASN.1 functions (e.g., 'd2i_X509', 'd2i_PKCS12', etc.) nor are applications using only PEM functions.
