Package        : prosody
Version        : 0.9.12-2+deb9u3
CVE ID         : CVE-2021-32917 CVE-2021-32921

Two security issues have been discovered in prosody:

CVE-2021-32917

    The proxy65 component allows open access by default, even if neither of the
    users has an XMPP account on the local server, allowing unrestricted use of
    the server's bandwidth.

CVE-2021-32921

    Authentication module does not use a constant-time algorithm for comparing
    certain secret strings when running under Lua 5.2 or later. This can
    potentially be used in a timing attack to reveal the contents of secret
    strings to an attacker.

For Debian 9 stretch, these problems have been fixed in version
0.9.12-2+deb9u3.

We recommend that you upgrade your prosody packages.
