Prosody · Prosody · CVE-2021-32918
**Name of the Vulnerable Software and Affected Versions**
Prosody versions prior to 0.11.9
**Description**
An issue in Prosody allows remote unauthenticated denial-of-service (DoS) attacks via memory exhaustion when running under Lua 5.2 or Lua 5.3. The problem is related to an error in the resource control mechanism, which can be exploited by a remote attacker to cause a denial of service.
**Recommendations**
For versions prior to 0.11.9, update to version 0.11.9 or later to resolve the issue. As a temporary workaround, consider restricting default settings to prevent memory exhaustion until a patch is applied.
