There is no fixed version for Debian:13 libcrypt-openssl-pkcs12-perl.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libcrypt-openssl-pkcs12-perl package and not the libcrypt-openssl-pkcs12-perl package as distributed by Debian.
See How to fix? for Debian:13 relevant fixed versions and status.
Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl have out-of-bounds (OOB) write flaws.
When parsing a PKCS12 file, with a >= 1 GiB OCTET STRING (or BIT STRING) attribute on a SAFEBAG, via info() or info_as_hash(), a heap out-of-bounds write would be triggered with remote-code-execution potential (RCE) due to a signed integer overflow in the size calculation passed to Renew().
