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.
AnalysisAI
Heap out-of-bounds read in the Perl module Crypt::OpenSSL::PKCS12 before version 1.96 lets a crafted PKCS#12 file leak adjacent process heap memory into Perl scalars when its attributes are printed. Because print_attribute() copies a UTF8STRING value with strncpy into a buffer sized to the exact declared length and never NUL-terminates it, downstream strlen()/newSVpvn() reads past the buffer end. No public exploit identified at time of analysis, EPSS is low (0.35%), and it is not on CISA KEV, but the SSVC framework flags it as automatable with partial technical impact.
