Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2022-24773)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to signature verification code does not properly check `DigestInfo` for a proper ASN.1 structure. A remote unauthenticated attacker can get a successful verification with signatures that contain invalid structures but a valid digest
2) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2022-24772)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to incorrect RSA PKCS#1 v1.5 signature verification caused by a missing check or tailing garbage bytes after decoding a `DigestInfo` ASN.1 structure. A remote attacker can forge a signature and perform a man-in-the-middle (MitM) attack.
3) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2022-24771)
The vulnerability allows a remote attacker to bypass security restrictions.
The vulnerability exists due to a improper signature verification when checking the digestAlgorithm structure. A remote unauthenticated attacker can use a specially-crafted structure to steal padding bytes and use unchecked portion of the PKCS#1 encoded message to exploit this vulnerability and forge a signature when a low public exponent is being used.
