The remote Debian host is missing a security-related update.


It was discovered that the Key Distribution Center (KDC) in Kerberos 5 crashes when processing certain crafted requests :

- CVE-2011-1528 When the LDAP backend is used, remote users can trigger a KDC daemon crash and denial of service.

- CVE-2011-1529 When the LDAP or Berkeley DB backend is used, remote users can trigger a NULL pointer dereference in the KDC daemon and a denial of service.

The oldstable distribution (lenny) is not affected by these problems.


Upgrade the krb5 packages.

For the stable distribution (squeeze), these problems have been fixed in version 1.8.3+dfsg-4squeeze5.
