Greg Roelofs updated HADOOP-6966:
---------------------------------
Attachment: bzip2-1.0.6-CVE-2010-0405.patch.txt
H-6966.v1.trunk-hadoop-common.patch.txt
Relevant portion of bzip2 1.0.6 patch for CVE-2010-0405, and untested (not even
compiled) port of it to Hadoop trunk.
I've also added a credit that I suspect should have been added long ago (but in
any case is relevant to this patch) and marked three of the missing
bounds-check locations without actually attempting to fix them. (They're all
trivial, I think, just tedious; and I don't have time at the moment to finish
this off.)

> The bzip2 Java port by Keiron Liddle appears to be very closely related to
> the bzip2/libbzip2 C code, but it is missing a number of data-integrity
> checks present in the latter (including today's fix for CVE-2010-0405).
> Java may be immune to C-style buffer overruns, but the data-corruption
> possibility remains. I believe most of the 20+ BZ_DATA_ERROR checks in
> decompress.c are appropriate in the Ant/Hadoop port.
