    SVGAlib, discovered that temporary files are created in an insecure
    fashion.  A malicious local user could cause arbitrary files to be
    overwritten by a symlink attack.
    
    For the stable distribution (woody) this problem has been
    fixed in version 1.2-14.2.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 1.2-17.
    
    We recommend that you upgrade your bmv packages.
