    Tavis Ormandy discovered that the embedded GD library copy in libwmf,
    a library to parse windows metafiles (WMF), makes use of a pointer
    after it was already freed.  An attacker using a crafted WMF file can
    cause a denial of service or possibly the execute arbitrary code via
    applications using this library.
    
    
    For the oldstable distribution (etch), this problem has been fixed in
    version 0.2.8.4-2+etch1.
    
    For the stable distribution (lenny), this problem has been fixed in
    version 0.2.8.4-6+lenny1.
    
    For the testing distribution (squeeze), this problem will be fixed soon.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 0.2.8.4-6.1.
    
    
    We recommend that you upgrade your libwmf packages.
