Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. For the 1.0.2 release it is
 addressed in git commit 6fc1aaaf3 that is available to premium support customers only. It will be made
 available in 1.0.2zc when it is released. The issue only affects OpenSSL on MIPS platforms. Fixed in
 OpenSSL 3.0.1 (Affected 3.0.0). Fixed in OpenSSL 1.1.1m (Affected 1.1.1-1.1.1l). Fixed in OpenSSL 1.0.2zc-
 dev (Affected 1.0.2-1.0.2zb). (CVE-2021-4160)

Solution

Update the openssl-1.0.1g library and its related packages to version 1.0.1g+e1 or later.
