Summary

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.
