Description:
Multiple vulnerabilities have been identified in Speak Freely allowing malicious people to gain access to the system running Speak Freely.
A buffer overflow has been identified in the handling of UDP packets with the "faceRequest" bit set.
A buffer overflow has been identified in the handling of VAT protocol packets. If the user name is longer than 256 characters it will overflow the buffer.
A buffer overflow has been identified in the decompression of audio packets.
The buffer overflows could possibly be exploited to gain system access.
A race condition exists when using PGP allowing malicious local users to overwrite arbitrary files which the user running Speak Freely got access to. The problem occurs because Speak Freely uses "/tmp" in an insecure manner with predictable filenames.
Speak Freely can be used to relay UDP packets due a function allowing packets to be echoed back to the sender. As UDP can easily be spoofed this could be used to send traffic to third parties.
Solution:
All vulnerabilities but the UDP relaying has been fixed in version 7.6
It has not been proved that the UDP relaying could be used maliciously to anything but consuming bandwidth.
