Title:
Refresh hangs due to strdup on non-NULL terminated string
Status in appstream package in Ubuntu:
Fix Committed
Status in appstream source package in Xenial:
Fix Committed
Bug description:
[Impact]
* The cache refresh is blocked on a strdup on a non-NULL-terminated string
in some very rare occasions (very rare because this bug is present for almost
3y without a single report).
* Fixing this bug resolves the issue for people who might experience it.
* See https://github.com/ximion/appstream/issues/35 for details.
[Test Case 1]
* Run `sudo appstreamcli refresh --force`
* The AppStream cache should be updated, no change in behavior should be
seen.
[Test Case 2]
* In case you were experiencing the almost-infinite hang when running
`sudo appstreamcli refresh --force`, this issue should be fixed with
the SRU.
[Regression Potential]
* Very low, since this only fixes the decompression code. There
should be no sideeffects of that (given that the patch itself doesn't
break anything, which it shouldn't, since it has been tested upstream
for a while)
[Other Info]
* This fix has been applied upstream:
https://github.com/ximion/appstream/commit/f33c520c37e2ba51d92402220250b8d501a2bf43
* A smaller version of the patch (one-liner) is available, at the expense of
not having reduced memory usage:
