Hello Maxim,
thank you for the clarification, appreciated.
Just one clarification, my comment regarding the advisory from 2018 was not meant as advertisement etc..
One suggestion to objectify the whole discussion, there exists a well-known and accepted metric for vulnerabilities: CVSS [1]
If I calculate the CVSS score for this issue, it results in a medium level with score 5.8. But this is of course again (at least somewhat) influenced from my point of view to this bug.
Some projects have a policy to only do a security announcement for vulnerabilities with score high and critical. For Kamailio this is not yet defined in a detailed way, due to the size of the project and other factors.
So, If people in this discussion (or other people on the list) are interested in improving the project security processes – this wiki page with the current process might be a good starting point: https://www.kamailio.org/wiki/security/policy
Please suggest your improvements to the existing process (preferable in a new discussion thread) on the sr-dev list. If you want to do it in private, feel free contact the management list.
Publishing security vulnerabilities
Kamailio will publish security vulnerabilities, including an CVE ID, on the kamailio-business mailing list, sr-dev, sr-users as well as related lists. The advisories will also be published on the kamailio.org web site.CVE entries should be created for vulnerabilities in the core and major modules, for rarely used modules this is not necessary. If there are several security issues together in one release, they should be announced together.
