Alpine: multiple libzmq packages, multiple zeromq packages: security update to 4.3.1-r0

high Tenable Cloud Security Plugin ID 424744

Description

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

 - A pointer overflow, with code execution, was discovered in ZeroMQ libzmq (aka 0MQ) 4.2.x and 4.3.x before
 4.3.1. A v2_decoder.cpp zmq::v2_decoder_t::size_ready integer overflow allows an authenticated attacker to
 overwrite an arbitrary amount of bytes beyond the bounds of a buffer, which can be leveraged to run
 arbitrary code on the target system. The memory layout allows the attacker to inject OS commands into a
 data structure located immediately after the problematic buffer (i.e., it is not necessary to use a
 typical buffer-overflow exploitation technique that changes the flow of control). (CVE-2019-6250)
