Detailsinfo

A vulnerability was found in JONASBN Crypt::OpenSSL::PKCS12 up to 1.95 on Perl. It has been rated as problematic. Affected by this issue is the function print_attribute. The manipulation with an unknown input leads to a out-of-bounds vulnerability. Using CWE to declare the problem leads to CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality. CVE summarizes:

Crypt::OpenSSL::PKCS12 versions before 1.96 for Perl permits a heap OOB read in print_attribute UTF8STRING path. print_attribute() copies a UTF8STRING ASN.1 attribute value into a heap buffer sized exactly to its declared length via strncpy, leaving no NUL terminator. Downstream callers run strlen() on the result and pass the inflated length to newSVpvn(), copying attacker-influenced adjacent heap bytes into a Perl scalar.
