Package        : prosody
CVE ID         : CVE-2018-10847
Debian Bug     : 900524

It was discovered that Prosody, a lightweight Jabber/XMPP server, does
not properly validate client-provided parameters during XMPP stream
restarts, allowing authenticated users to override the realm associated
with their session, potentially bypassing security policies and allowing
impersonation.

Details can be found in the upstream advisory at
https://prosody.im/security/advisory_20180531/

For the oldstable distribution (jessie), this problem has been fixed
in version 0.9.7-2+deb8u4.

For the stable distribution (stretch), this problem has been fixed in

We recommend that you upgrade your prosody packages.
