    CVE ID         : CVE-2024-42365 CVE-2024-42491


    Two issues have been found in asterisk, an Open Source Private Branch
    Exchange.


    CVE-2024-42365

        Due to a privilege escalation, remote code execution and/or
        blind server-side request forgery with arbitrary protocol are
        possible.

    CVE-2024-42491

        Due to bad handling of malformed Contact or Record-Route URI in an
        incoming  SIP request, Asterisk might crash when res_resolver_unbound
        is used.

    Thanks to Niels Galjaard, a minor privilege escalation has been fixed.
