high Nessus Plugin ID 25580
Synopsis
The remote CentOS host is missing one or more security updates.Description
Updated krb5 packages that fix several security flaws are now available for Red Hat Enterprise Linux 4 and 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 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. On Red Hat Enterprise Linux 4 and 5, glibc detects attempts to free invalid pointers. A remote unauthenticated attacker who can access kadmind could trigger this flaw and cause kadmind to crash. (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-based 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)
Users of krb5-server are advised to update to these erratum packages which contain backported fixes to correct these issues.
