Debian Security Advisory
DLA-2687-1 prosody -- LTS security update
- Date Reported:
- 16 Jun 2021
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2021-32917, CVE-2021-32921.
- More information:
Two security issues have been discovered in prosody:
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.
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.
