Overview

Affected versions of this package are vulnerable to Improper Input Validation. Lasso 2.2.1 and earlier does not properly check the return value from the OpenSSL DSA_verify function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077.
