Alpine: openssl: security update to 1.0.2t-r0

medium Tenable Cloud Security Plugin ID 406091

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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)

- In situations where an attacker receives automated notification of the success or failure of a decryption
attempt an attacker, after sending a very large number of messages to be decrypted, can recover a
CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted with the
public RSA key, using a Bleichenbacher padding oracle attack. Applications are not affected if they use a
certificate together with the private RSA key to the CMS_decrypt or PKCS7_decrypt functions to select the
correct recipient info to decrypt. 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-2019-1563)
