    Several issues have been discovered in mumble, a low latency VoIP
    client. The Common Vulnerabilities and Exposures project identifies the
    following issues:
    
    CVE-2014-0044
    
        It was discovered that a malformed Opus voice packet sent to a
        Mumble client could trigger a NULL pointer dereference or an
        out-of-bounds array access. A malicious remote attacker could
        exploit this flaw to mount a denial of service attack against a
        mumble client by causing the application to crash.
    
    CVE-2014-0445
    
        It was discovered that a malformed Opus voice packet sent to a
        Mumble client could trigger a heap-based buffer overflow. A
        malicious remote attacker could use this flaw to cause a client
        crash (denial of service) or potentially use it to execute
        arbitrary code.
    
    The oldstable distribution (squeeze) is not affected by these problems.
    
    For the stable distribution (wheezy), these problems have been fixed in
    version 1.2.3-349-g315b5f5-2.2+deb7u1.
    
    For the unstable distribution (sid), these problems will be fixed soon.
    
    We recommend that you upgrade your mumble packages.
