Alpine: multiple suricata packages: security update to 6.0.4-r0

critical Tenable Self-Hosted Container Security Plugin ID 407295

Description

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

 - Suricata before 5.0.8 and 6.x before 6.0.4 allows TCP evasion via a client with a crafted TCP/IP stack
 that can send a certain sequence of segments. (CVE-2021-37592)

 - An issue was discovered in Suricata before 6.0.4. It is possible to bypass/evade any HTTP-based signature
 by faking an RST TCP packet with random TCP options of the md5header from the client side. After the
 three-way handshake, it's possible to inject an RST ACK with a random TCP md5header option. Then, the
 client can send an HTTP GET request with a forbidden URL. The server will ignore the RST ACK and send the
 response HTTP packet for the client's request. These packets will not trigger a Suricata reject action.
 (CVE-2021-45098)
