"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-2014-0045
    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."
