The Common Vulnerabilities and Exposures project identifies the following problems:
CVE-2007-0956
It was discovered that the krb5 telnet daemon performs insufficient validation of usernames, which might allow unauthorized logins or privilege escalation.
CVE-2007-0957
iDefense discovered that a buffer overflow in the logging code of the KDC and the administration daemon might lead to arbitrary code execution.
CVE-2007-1216
It was discovered that a double free in the RPCSEC_GSS part of the GSS library code might lead to arbitrary code execution.
For the stable distribution (sarge) these problems have been fixed in version 1.3.6-2sarge4.
For the upcoming stable distribution (etch) these problems have been fixed in version 1.4.4-7etch1.
For the unstable distribution (sid) these problems will be fixed soon.
We recommend that you upgrade your Kerberos packages.");
