Bug description:
Distribution: Ubuntu 16.04 x64 (Flavour: KDE Neon User Edition 5.10)
linux-image-4.4.0-81-generic appears to contain a regression, probably
related to the CVE-2017-1000364 fix backport / patch.
Using this kernel, the Oracle Java browser plugin always crashes
during stack-related actions on initialization. This means, the plugin
completely stopped working.
It works perfectly fine in linux-image-4.4.0-79-generic (vurlerable to
CVE-2017-1000364) as well as linux-image-4.11.6-041106-generic, which also
contains a fix for CVE-2017-1000364.
uname -a:
> Linux Zweiblum 4.4.0-81-generic #104-Ubuntu SMP Wed Jun 14 08:17:06
UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
I tested Oracle Java 1.8 u131 as well as 1.6 u64 in Firefox 51.0.1 as
well as Iceweasel / Firefox/3.5.16 in a chroot.
Using linux-image-4.4.0-81-generic it crashes in all combinations
while with both other kernels it works.
I was not able to obtain any detailed crash information from Firefox 51.0.1,
but Iceweasel 3.5.16 crashed completely, allowing me to obtain a stack trace
which shows the relation to stack operations performed by the plugin, even
without proper debug symbols:
> (gdb) bt full
> #0 0x00007fa06d805307 in _expand_stack_to(unsigned char*) () from
/opt/java-8-oracle/jre/lib/amd64/server/libjvm.so

/opt/java-8-oracle/jre/lib/amd64/server/libjvm.so

> #4 <signal handler called>
I first assumed a bug in the Java plugin, but it works fine in Linux 4.11.6.
The crash will be triggered by any applet, for example the test applet at:

I'm running the Ubuntu 16.04 based KDE Neon distribution which somehow
apparently does not allow me to use apport to report this bug:

If someone can tell me how to get apport working for this package, I
can use it to collect additional information, but (unfortunately?) the
problem should be fairly easy to reproduce...
