carry-propagating bug

There is a carry propagation bug in the MIPS32 and MIPS64 squaring
procedure. Many EC algorithms are affected, including some of the
TLS 1.3 default curves. Impact was not analyzed in detail, because the
pre-requisites for attack are considered unlikely and include reusing
private keys. Analysis suggests that attacks against RSA and DSA as
a result of this defect would be very difficult to perform and are
not believed likely. Attacks against DH are considered just feasible
(although very difficult) because most of the work necessary to deduce
information about a private key may be performed offline. The amount of
resources required for such an attack would be significant. However,
for an attack on TLS to be meaningful, the server would have to share
the DH private key among multiple clients, which is no longer an option
since CVE-2016-0701.

This issue affects OpenSSL versions 1.0.2, 1.1.1 and 3.0.0. It was
addressed in the releases of 1.1.1m and 3.0.1 on the 15th of December 2021,
and the release of 1.0.2zc on the 22nd of February 2022.

The issue only affects OpenSSL on MIPS platforms.
