Mumble, voice chat app for gamer, released version 1.3.4 with important bug-fixes.

Mumble is a free and open-source VoIP application designed for use by gamer and is similar to programs such as TeamSpeak.

Before, the public server list registration script doesn’t have an URL scheme whitelist for the website field. So a malicious server can register itself with a dangerous URL in an attempt to attack a user’s machine. In Mumble 1.3.4, now it only allows http and https schemes in both client-side and public server lists.

The new release also fixed an issue that applying a noise gate generates significant packet loss. Due to the mitigation for vulnerabilities discovered in OCB2, it allows some packets with specific characteristics to be dropped during encryption. It however causes packet loss issue. Now it is fixed by a workaround from contributor.

Other changes in Mumble 1.3.4 include:

  • Don’t use outdated (non-existent) notification icon names on Linux.
  • Use qInfo instead of qFatal for logging, which fixes a crash issues.

Unfortunately, there are still known issues in Mumble that overlay blocked by CS:GO Trusted Mode and BattleEye.
