cyrus-sasl-2.1.28

[Bruce Dubbs]

New point version.

[Douglas R. Reno]

Includes two CVEs - CVE-2019-19906 (denial of service) and CVE-2022-24407 (password escape for SQL insert/update commands). Due to CVE-2022-24407 and the fact that Ubuntu/Debian/Fedora have released updates for this, promoting to High.
