Package : krb5
CVE ID : CVE-2015-2697
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.
