    Yves Orton discovered a flaw in the rehashing code of Perl. This flaw
    could be exploited to carry out a denial of service attack against code
    that uses arbitrary user input as hash keys. Specifically an attacker
    could create a set of keys of a hash causing a denial of service via
    memory exhaustion.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 5.10.1-17squeeze6.
    
    For the testing distribution (wheezy), and the unstable distribution
    (sid), this problem has been fixed in version 5.14.2-19.
    
    We recommend that you upgrade your perl packages.
