(Samba: Multiple vulnerabilities)

    Samba fails to do proper bounds checking when handling
    TRANSACT2_QFILEPATHINFO replies. Additionally an input validation flaw
    exists in ms_fnmatch.c when matching filenames that contain wildcards.
  
Impact :

    An attacker may be able to execute arbitrary code with the permissions
    of the user running Samba. A remote attacker may also be able to cause
    an abnormal consumption of CPU resources, resulting in slower
    performance of the server or even a Denial of Service.
  
Workaround :

    There is no known workaround at this time."
