This fixes 4 security vulnerabilities/bugs:
- CVE-2021-2839 - SSLv2 vulnerability. Openssl 1.1.1 does not support
SSLv2, but the affected functions still exist. Considered just a bug.
- CVE-2021-2840 - calls EVP_CipherUpdate, EVP_EncryptUpdate and
EVP_DecryptUpdate may overflow the output length argument in some
cases where the input length is close to the maximum permissable
length for an integer on the platform. In such cases the return value
from the function call will be 1 (indicating success), but the output
length value will be negative.
- CVE-2021-2841 - The X509_issuer_and_serial_hash() function attempts to
create a unique hash value based on the issuer and serial number data
contained within an X509 certificate. However it was failing to
correctly handle any errors that may occur while parsing the issuer
field (which might occur if the issuer field is maliciously
constructed). This may subsequently result in a NULL pointer deref and
a crash leading to a potential denial of service attack.
- Fixed SRP_Calc_client_key so that it runs in constant time. This could
be exploited in a side channel attack to recover the password.
The 3 CVEs above are currently awaiting analysis.
