There is NO 2.0.34 yet.
Alan Cox has made some prepatches (not official).
They fix some memory bugs, a lot of network(driver) updates, Documentation
updates, Native language codepages and Unicode support, ext2fs bugfix,
scsi bugfixes/upgrades enz.
You can find his latest prepatch (2.0.34pre8) at
ftp.uk.linux.org:/pub/linux/incoming.
It has to be applied to a clean 2.0.33

Note that last night on bugtraq the following came by (this one is not in
2.0.34pre8 yet):

There's an 'off by one IP header' bug
