    Debian Bug     : 803088
    
    Marc Deslauriers reported that the update for krb5 issued as DSA-3395-1
    did not contain the patch to address CVE-2015-2697 for the packages
    built for the oldstable distribution (wheezy). Updated packages are now
    available to address this issue. For reference, the relevant part of the
    original advisory text follows.
    
    CVE-2015-2697
    
        It was discovered that the build_principal_va() function incorrectly
        handles input strings. An authenticated attacker can take advantage
        of this flaw to cause a KDC to crash using a TGS request with a
        large realm field beginning with a null byte.
    
    For the oldstable distribution (wheezy), this problem has been fixed
    in version 1.10.1+dfsg-5+deb7u6.
    
    We recommend that you upgrade your krb5 packages.
