A vulnerability in the linux kernel function mremap() has been found. This vulnerability could be exploited by a local attacker to gain root privileges on a system where they already have a user account.
This bug has been fixed in the mainline 2.4.24 kernel; the fix has been backported to 2.4.19 for NetWinder since the later kernels are not yet fully stable on ARM platform.
Download the following RPM packages to the NetWinder into a temporary
directory, then install them with the command "rpm -Uvh *.rpm". Be sure
there are no other files ending in ".rpm" in the temporary directory. See
http://www.netwinder.org/security/install.html for more help.
