"Several vulnerabilities have been discovered in nas, the Network Audio
System.

  - CVE-2007-1543
    A stack-based buffer overflow in the accept_att_local
    function in server/os/connection.c in nas allows remote
    attackers to execute arbitrary code via a long path
    slave name in a USL socket connection.

  - CVE-2007-1544
    An integer overflow in the ProcAuWriteElement function
    in server/dia/audispatch.c allows remote attackers to
    cause a denial of service (crash) and possibly execute
    arbitrary code via a large max_samples value.

  - CVE-2007-1545
    The AddResource function in server/dia/resource.c allows
    remote attackers to cause a denial of service (server
    crash) via a nonexistent client ID.

  - CVE-2007-1546
    An array index error allows remote attackers to cause a
    denial of service (crash) via (1) large num_action
    values in the ProcAuSetElements function in
    server/dia/audispatch.c or (2) a large inputNum
    parameter to the compileInputs function in
    server/dia/auutil.c.

  - CVE-2007-1547
    The ReadRequestFromClient function in server/os/io.c
    allows remote attackers to cause a denial of service
    (crash) via multiple simultaneous connections, which
    triggers a NULL pointer dereference."
