1.3.0 - 2022-03-17

Security

• Three RSA PKCS#1 v1.5 signature verification issues were reported by Moosa Yahyazadeh (moosa-yahyazadeh@uiowa.edu).
• HIGH: Leniency in checking digestAlgorithm structure can lead to signature forgery.
  • The code is lenient in checking the digest algorithm structure. This can allow a crafted structure that steals padding bytes and uses unchecked portion of the PKCS#1 encoded message to forge a signature when a low public exponent is being used. For more information, please see "Bleichenbacher's RSA signature forgery based on implementation error" by Hal Finney.
  • CVE ID: CVE-2022-24771
  • GHSA ID: GHSA-cfm4-qjh2-4765
• HIGH: Failing to check tailing garbage bytes can lead to signature forgery.
  • The code does not check for tailing garbage bytes after decoding a DigestInfo ASN.1 structure. This can allow padding bytes to be removed and garbage data added to forge a signature when a low public exponent is being used. For more information, please see "Bleichenbacher's RSA signature forgery based on implementation error" by Hal Finney.
  • CVE ID: CVE-2022-24772
  • GHSA ID: GHSA-x4jg-mjrx-434g
• MEDIUM: Leniency in checking type octet.
  • DigestInfo is not properly checked for proper ASN.1 structure. This can lead to successful verification with signatures that contain invalid structures but a valid digest.
  • CVE ID: CVE-2022-24773
  • GHSA ID: GHSA-2r2c-g63r-vccr

Fixed

• [asn1] Add fallback to pretty print invalid UTF8 data.
• [asn1] fromDer is now more strict and will default to ensuring all input bytes are parsed or throw an error. A new option parseAllBytes can disable this behavior.
  • NOTE: The previous behavior is being changed since it can lead to security issues with crafted inputs. It is possible that code doing custom DER parsing may need to adapt to this new behavior and optional flag.
• [rsa] Add and use a validator to check for proper structure of parsed ASN.1 RSASSA-PKCS-v1_5 DigestInfo data. Additionally check that the hash algorithm identifier is a known value from RFC 8017 PKCS1-v1-5DigestAlgorithms. An invalid DigestInfo or algorithm identifier will now throw an error.
  • NOTE: The previous lenient behavior is being changed to be more strict since it could lead to security issues with crafted inputs. It is possible that code may have to handle the errors from these stricter checks.
