Detail
Problem Description: Updated krb5 packages that fix several security flaws are now available for Red Hat Enterprise Linux 2.1 and 3. This update has been rated as having critical security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 3. Problem description: Kerberos is a network authentication system which allows clients and servers to authenticate to each other through use of symmetric encryption and a trusted third party, the KDC. kadmind is the KADM5 administration server. David Coffey discovered an uninitialized pointer free flaw in the RPC library used by kadmind. A remote unauthenticated attacker who can access kadmind could trigger this flaw and cause kadmind to crash or potentially execute arbitrary code as root. (CVE-2007-2442) David Coffey also discovered an overflow flaw in the RPC library used by kadmind. On Red Hat Enterprise Linux, exploitation of this flaw is limited to a denial of service. A remote unauthenticated attacker who can access kadmind could trigger this flaw and cause kadmind to crash. (CVE-2007-2443) A stack buffer overflow flaw was found in kadmind. An authenticated attacker who can access kadmind could trigger this flaw and potentially execute arbitrary code on the Kerberos server. (CVE-2007-2798) For Red Hat Enterprise Linux 2.1, several portability bugs which would lead to unexpected crashes on the ia64 platform have also been fixed. Users of krb5-server are advised to update to these erratum packages which contain backported fixes to correct these issues. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188 5. Bug IDs fixed (http://bugzilla.redhat.com/): 241590 - kadmin core dumps on ia64 245547 - CVE-2007-2442 krb5 RPC library unitialized pointer free 245548 - CVE-2007-2443 krb5 RPC library stack overflow 245549 - CVE-2007-2798 krb5 kadmind buffer overflow |
