Detail
| In certain application programs packaged in the MIT Kerberos 5 source distribution, calls to setuid() and seteuid() are not always checked for success and which may fail with some PAM configurations. A local user could exploit one of these vulnerabilities to result in privilege escalation. No exploit code is known to exist at this time. For the stable distribution (sarge) these problems have been fixed in version 1.3.6-2sarge3. For the unstable distribution (sid) these problems have been fixed in version 1.4.3-9. We recommend that you upgrade your krb5 packages. |
