Description Mark J. Cox 2005-10-21 08:32:46 EDT
CVE-2005-3274 states:
        Race condition in ip_vs_conn_flush in Linux 2.6 before 2.6.13
        and 2.4 before 2.4.32-pre2, when running on SMP systems,
        allows local users to cause a denial of service (null
        dereference) by causing a connection timer to expire while the
        connection table is being flushed before the appropriate lock
        is acquired.


This issue looks to affect rhel2.1 ipf because of the backport of ipvs in

Note for RHEL3 we updated the similar backported patch we included for U6.
RHEL2.1 x86 does not look vulnerable as it uses a more outdated version of the
ipvs code.
