Jan Kara did some fixes in the UDF fs and they were committed to mainline already, both actual bugfixes and some more sanity checking for hardening. Buffer overreads or overwrites would have been possible. I think a single CVE is sufficient. The two mainline commits: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=1df2ae31c724e57be9d7ac00d78db8a5dabdd050 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=adee11b2085bee90bd8f4f52123ffb07882d6256 commit 1df2ae31c724e57be9d7ac00d78db8a5dabdd050 Author: Jan Kara <jack@...e.cz> Date: Wed Jun 27 21:23:07 2012 +0200 udf: Fortify loading of sparing table Add sanity checks when loading sparing table from disk to avoid accessing unallocated memory or writing to it.

Signed-off-by: Jan Kara <jack@...e.cz> Ciao, Marcus
