+Description:
+ A race condition in the way env_start and env_end pointers are
+ initialized in the execve system call and used in fs/proc/base.c
+ on Linux 2.4 allows local users to cause a denial of service
+ (crash).
+Notes:
+ The fix for 2.4 went into a larger patch:
+ http://linux.bkbits.net:8080/linux-2.4/cset@41c68e9bogrpceA9rUJa-xHwBd-P6g?nav=index.html|src/|src/fs|src/fs/proc|related/fs/proc/base.c
+ However, the patch for 2.6 is much simpler:
+ http://linux.bkbits.net:8080/linux-2.6/cset@3ff1101fZfOZMtqtcvKc_s-agJpLrQ?nav=index.html|src/|src/fs|src/fs/proc|related/fs/proc/base.c
+ Unfortunately, it doesn't apply cleanly to 2.4. It looks like
+ the fix included in 2.4.18-10 just re-typed len in
+ proc_pid_environ; while in 2.6 len was also retyped in
+ proc_pid_cmdline. Only the former deals with evn_end/env_start
+ pointers and the latter doesn't apply cleanly to 2.4, so I'm
+ just making the proc_pid_environ change.
+ .
+ hrm.. maybe there was an earlier patch to 2.4; the above 2.4
+ patch didn't go in till 2.4.29, yet it looks like this was
+ already fixed in our 2.4.27 .orig.tar.gz
+ .
+ jmm> I assume this was fixed upstream in 2.4.22-pre10?
