Bug#1031046: Only include in Bookworm with commitment to stable updates

[Moritz Muehlenhoff]

Source: asterisk
Version: 1:20.1.0~dfsg+~cs6.12.40431414-1
Severity: serious

Asterisk should only be included in Bookworm with a reliable commitment
by the maintainers to backport/test security fixes across the typical
three year life cycle (two years of stable-security and one year of
oldstable-security). (There have been 37 CVEs in 2021/2022)

Cheers,
        Moritz
