Alpine: libcrypto3, multiple openssl packages: security update to 1.0.2-r0 (deprecated)

medium Tenable Self-Hosted Container Security Plugin ID 400775

Description

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

- OpenSSL 1.0.2 (starting from version 1.0.2b) introduced an "error state" mechanism. The intent was that if
a fatal error occurred during a handshake then OpenSSL would move into the error state and would
immediately fail if you attempted to continue the handshake. This works as designed for the explicit
handshake functions (SSL_do_handshake(), SSL_accept() and SSL_connect()), however due to a bug it does not
work correctly if SSL_read() or SSL_write() is called directly. In that scenario, if the handshake fails
then a fatal error will be returned in the initial function call. If SSL_read()/SSL_write() is
subsequently called by the application for the same SSL object then it will succeed and the data is passed
without being decrypted/encrypted directly from the SSL/TLS record layer. In order to exploit this issue
an application bug would have to be present that resulted in a call to SSL_read()/SSL_write() being issued
after having already received a fatal error. OpenSSL version 1.0.2b-1.0.2m are affected. Fixed in OpenSSL
1.0.2n. OpenSSL 1.1.0 is not affected. (CVE-2017-3737)

- There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with
1024-bit moduli. No EC algorithms are affected. 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
DH1024 are considered just feasible, 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 DH1024
private key among multiple clients, which is no longer an option since CVE-2016-0701. This only affects
processors that support the AVX2 but not ADX extensions like Intel Haswell (4th generation). Note: The
impact from this issue is similar to CVE-2017-3736, CVE-2017-3732 and CVE-2015-3193. OpenSSL version
1.0.2-1.0.2m and 1.1.0-1.1.0g are affected. Fixed in OpenSSL 1.0.2n. Due to the low severity of this issue
we are not issuing a new release of OpenSSL 1.1.0 at this time. The fix will be included in OpenSSL 1.1.0h
when it becomes available. The fix is also available in commit e502cc86d in the OpenSSL git repository.
