Subject: [SECURITY] [DLA 1058-1] krb5 security update

Package : krb5
Version : 1.10.1+dfsg-5+deb7u8
CVE ID : CVE-2017-11368
Debian Bug : 869260

In MIT Kerberos 5 (aka krb5) 1.7 and later, an authenticated attacker
can cause a KDC assertion failure by sending invalid S4U2Self or
S4U2Proxy requests.

For Debian 7 "Wheezy", these problems have been fixed in version
1.10.1+dfsg-5+deb7u8.

We recommend that you upgrade your krb5 packages.
