flashplugin-nonfree has memory leak

[Géza Búza]

Binary package hint: flashplugin-nonfree

1)
Description: Ubuntu 11.04
Release: 11.04

2)
flashplugin-nonfree:
10.3.181.26ubuntu0.11.04.1

3)
I started Firefox 4.01 and opened the following address:
http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx
I expected the page to be loaded as usual.

4)
Loading of the page stopped at one point. From here Ubuntu not responded to anything (keystrokes, mouse move etc.).

I figured out that Firefox's plugin-container process eats all available memory (See attached output of top).
I tried to open that page with Opera 11.11 and the same happened. So it's not Firefox related.

I am wondering the kernel's oom killer why didn't killed the plugin-container process. Even I had tried to change the default overcommit settings to vm.overcommit_memory = 2 and vm.overcommit_ratio = 50, but it wasn't helped. So maybe there is a kernel bug too.

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

That distro have reached EOL since a while; and such problem has been resolved long time ago.
