Description:	Summary: The remote host is missing an update for the Debian 'krb5' package(s) announced via the DSA-2518-1 advisory. Vulnerability Insight: Emmanuel Bouillon from NCI Agency discovered multiple vulnerabilities in MIT Kerberos, a daemon implementing the network authentication protocol. CVE-2012-1014 By sending specially crafted AS-REQ (Authentication Service Request) to a KDC (Key Distribution Center), an attacker could make it free an uninitialized pointer, corrupting the heap. This can lead to process crash or even arbitrary code execution. This CVE only affects testing (wheezy) and unstable (sid) distributions. CVE-2012-1015 By sending specially crafted AS-REQ to a KDC, an attacker could make it dereference an uninitialized pointer, leading to process crash or even arbitrary code execution In both cases, arbitrary code execution is believed to be difficult to achieve, but might not be impossible. For the stable distribution (squeeze), this problem has been fixed in version 1.8.3+dfsg-4squeeze6. For the testing distribution (wheezy), this problem has been fixed in version 1.10.1+dfsg-2. For the unstable distribution (sid), this problem has been fixed in version 1.10.1+dfsg-2. We recommend that you upgrade your krb5 packages. Affected Software/OS: 'krb5' package(s) on Debian 6. Solution: Please install the updated package(s). CVSS Score: 9.3 CVSS Vector: AV:N/AC:M/Au:N/C:C/I:C/A:C
