    Mark Martinec discovered that Perl incorrectly clears the tainted flag
    on values returned by case conversion functions such as "lc".  This
    may expose preexisting vulnerabilities in applications which use these
    functions while processing untrusted input.  No such applications are
    known at this stage.  Such applications will cease to work when this
    security update is applied because taint checks are designed to
    prevent such unsafe use of untrusted input data.
    
    For the oldstable distribution (lenny), this problem has been fixed in
    version 5.10.0-19lenny4.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 5.10.1-17squeeze1.
    
    For the testing distribution (wheezy), this problem has been fixed in
    version .
    
    For the testing distribution (wheezy) and the unstable distribution
    (sid), this problem has been fixed in version 5.10.1-20.
    
    We recommend that you upgrade your perl packages.
