Title:
Probable regression with EXT3 file systems and CVE-2018-1093 patches
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Trusty:
Fix Released
Bug description:
== SRU Justification ==
Mainline commit 7dac4a1726a9 introduced a regression in v4.17-rc1, which
made it's way into Trusty via upstream stable updates. This regression
is resolved by mainline commit 22be37acce25. This commit has been cc'd
to upstream stable, but has not made it's way into Trusty as of yet.
== Fix ==
22be37acce25 ("ext4: fix bitmap position validation")
== Regression Potential ==
Low. This commit has been cc'd to upstream stable, so it has had
additional upstream review.
== Test Case ==
A test kernel was built with this patch and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.
A customer reported on all of their ext3 and none of their ext4
systems that the file system was in read-only mode, I believe after
rebooting into 3.13.0-157.207 from 3.13.0-156.206. Here is the output
of tune2fs -l for one of the file systems:
