Echo: openssl-1.1.1c: security update to 1.1.1c+e1

medium Tenable Self-Hosted Container Security Plugin ID 478552

Description

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

- Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant
code paths. However, in some cases, it is possible to construct a group using explicit parameters (instead
of using a named curve). In those cases it is possible that such a group does not have the cofactor
present. This can occur even where all the parameters match a known named curve. If such a curve is used
then OpenSSL falls back to non-side channel resistant code paths which may result in full key recovery
during an ECDSA signature operation. In order to be vulnerable an attacker would have to have the ability
to time the creation of a large number of signatures where explicit parameters with no co-factor present
are in use by an application using libcrypto. For the avoidance of doubt libssl is not vulnerable because
explicit parameters are never used. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL
1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s). (CVE-2019-1547)

Solution

Update the openssl-1.1.1c library and its related packages to version 1.1.1c+e1 or later.
