SCA: security update for org.graylog2:graylog2-server (GHSA-g96c-x7rh-99r3)

medium Tenable Self-Hosted Container Security Plugin ID 415020

Description

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

 - Graylog is a free and open log management platform. Graylog makes use of only one single source port for
 DNS queries. Graylog binds a single socket for outgoing DNS queries and while that socket is bound to a
 random port number it is never changed again. This goes against recommended practice since 2008, when Dan
 Kaminsky discovered how easy is to carry out DNS cache poisoning attacks. In order to prevent cache
 poisoning with spoofed DNS responses, it is necessary to maximise the uncertainty in the choice of a
 source port for a DNS query. Although unlikely in many setups, an external attacker could inject forged
 DNS responses into a Graylog's lookup table cache. In order to prevent this, it is at least recommendable
 to distribute the DNS queries through a pool of distinct sockets, each of them with a random source port
 and renew them periodically. This issue has been addressed in versions 5.0.9 and 5.1.3. Users are advised
 to upgrade. There are no known workarounds for this issue. (CVE-2023-41045)
