CVE-2026-8507: Jonasbn crypt::openssl::pkcs12

Critical severity, CVSS 9.8. EPSS: 0.8% chance of exploitation in the next 30 days.

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().

Affected products
