Hi,

The following vulnerability was published for libcrypt-openssl-pkcs12-perl.

CVE-2026-9265[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
