    Several remote vulnerabilities have been discovered in the TFTP
    component of dnsmasq.  The Common Vulnerabilities and Exposures
    project identifies the following problems:
    
    CVE-2009-2957
      A buffer overflow in TFTP processing may enable arbitrary code
      execution to attackers which are permitted to use the TFTP service.
    
    CVE-2009-2958
      Malicious TFTP clients may crash dnsmasq, leading to denial of
      service.
    
    The old stable distribution is not affected by these problems.
    
    For the stable distribution (lenny), these problems have been fixed in
    version 2.45-1+lenny1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 2.50-1.
    
    We recommend that you upgrade your dnsmasq packages.
