Detail

a. Service Console package krb5 update to version krb5-1.2.7-70

Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography.

An input validation flaw in the asn1_decode_generaltime function in MIT Kerberos 5 before 1.6.4 allows remote attackers to cause a denial of service or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer.

A remote attacker could use this flaw to crash a network service using the MIT Kerberos library, such as kadmind or krb5kdc, by causing it to dereference or free an uninitialized pointer or, possibly, execute arbitrary code with the privileges of the user running the service.

NOTE: ESX by default is unaffected by this issue, the daemons kadmind and krb5kdc are not installed in ESX.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-0846 to this issue.

Title: DSA-1766-1 krb5 -- several
Description: Several vulnerabilities have been found in the MIT reference implementation of Kerberos V5, a system for authenticating users and services on a network. The Common Vulnerabilities and Exposures project identified the following problems: The Apple Product Security team discovered that the SPNEGO GSS-API mechanism suffers of a missing bounds check when reading a network input buffer which results in an invalid read crashing the application or possibly leaking information. Under certain conditions the SPNEGO GSS-API mechanism references a null pointer which crashes the application using the library. An incorrect length check inside the ASN.1 decoder of the MIT krb5 implementation allows an unauthenticated remote attacker to crash of the kinit or KDC program. Under certain conditions the the ASN.1 decoder of the MIT krb5 implementation frees an uninitialised pointer which could lead to denial of service and possibly arbitrary code execution. For the oldstable distribution, this problem has been fixed in version 1.4.4-7etch7. For the stable distribution, this problem has been fixed in version 1.6.dfsg.4~beta1-5lenny1. For the testing distribution, this problem will be fixed soon. For the unstable distribution, this problem has been fixed in version 1.6.dfsg.4~beta1-13. We recommend that you upgrade your krb5 packages.

Title: RHSA-2009:0408 -- krb5 security update (Important)
Description: Updated krb5 packages that fix various security issues are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. Kerberos is a network authentication system which allows clients and servers to authenticate to each other using symmetric encryption and a trusted third party, the Key Distribution Center (KDC). The Generic Security Service Application Program Interface (GSS-API) definition provides security services to callers (protocols) in a generic fashion. The Simple and Protected GSS-API Negotiation (SPNEGO) mechanism is used by GSS-API peers to choose from a common set of security mechanisms. An input validation flaw was found in the ASN.1 (Abstract Syntax Notation One) decoder used by MIT Kerberos. A remote attacker could use this flaw to crash a network service using the MIT Kerberos library, such as kadmind or krb5kdc, by causing it to dereference or free an uninitialized pointer.
