Debian DSA-520-1 : krb5 - buffer overflows

critical Nessus Plugin ID 15357

Synopsis

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

Description

In their advisory MITKRB5-SA-2004-001, the MIT Kerberos announced the existence of buffer overflow vulnerabilities in the krb5_aname_to_localname function. This function is only used if aname_to_localname is enabled in the configuration (this is not enabled by default).

Solution

For the current stable distribution (woody), this problem has been fixed in version 1.2.4-5woody5.

We recommend that you update your krb5 package.
