Vulnerability from cvelistv5 – Published: 2026-05-17 18:43 – Updated: 2026-05-18 12:55

Title

Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl have out-of-bounds (OOB) write flaws

Summary

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().

Severity

GHSA-3QMJ-QW66-FWX8

Vulnerability from github – Published: 2026-05-17 21:30 – Updated: 2026-05-18 15:30

Details

Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl have out of bound (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-OOB-WRITE would be triggered which could have Remote Code Execution (RCE) potential.

Severity

9.8 (Critical)
