The defect also allows forging signatures that lack the required minimum eight bytes of padding, creating a Bleichenbacher\u2011style forgery path. Consequently, any system that relies on forge to verify signed data can be deceived into accepting attacker\u2011generated signatures, potentially compromising authentication or integrity of protected content.", "risk_and_exploitability": "With a CVSS base score of 7.5, the vulnerability poses a high impact.
