    It was discovered that suphp, an Apache module to run PHP scripts with
    owner permissions handles symlinks insecurely, which may lead to
    privilege escalation by local users.
    
    For the stable distribution (etch), this problem has been fixed in
    version 0.6.2-1+etch0.
    
    For the unstable distribution (sid), this problem will be fixed soon.
    
    We recommend that you upgrade your suphp packages.
