Description
From CVE.org
Memory leak in the appletalk subsystem in the Linux kernel 2.4.x through 2.4.37.6 and 2.6.x through 2.6.31, when the appletalk and ipddp modules are loaded but the ipddp"N" device is not found, allows remote attackers to cause a denial of service (memory consumption) via IP-DDP datagrams.
Statement
Red Hat is aware of this issue. Please see https://access.redhat.com/articles/19069
This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 4 and 5, as the affected driver is not enabled in these kernels. The affected driver is available in Red Hat Enterprise MRG. It is also available in Red Hat Enterprise Linux 3, but only if the kernel-unsupported package is installed. Future kernel updates in Red Hat Enterprise Linux 3 and Red Hat Enterprise MRG will address this issue.
