[Secure-testing-team] Bug#837178: linux-image-3.16.0-4-amd64: All memory and swap is used up until system freezes

Package: src:linux
Version: 3.16.7-ckt25-2+deb8u3
Severity: critical
Tags: security
Justification: causes serious data loss
Dear Maintainer,
when I open a particular word document (it contains images and I can send it
to you for testing) with libreoffice, all memory and all swap get used up
within about a minute. This happens slowly enough that it can be monitored
with "top" and "free". What I see with top is that soffice.bin (which is
libreoffice) does not use much memory (maybe 2%). Nevertheless more and more
memory gets used. "free -h" gives something like this:
total used free shared buffers cached
Mem: 7.5G 7.4G 141M 5.9G 71M 6.4G
-/+ buffers/cache: 917M 6.6G
Swap: 8.0G 663M 7.4G
Eventually the "used" column in the "Mem:" and "Swap:" and lines reach the
total and the system runs out of memory and becomes totally unresponsive
(even the mouse pointer freezes), no remote logins are possible at this
point, and all keypresses are ignored. The only way to regain control is by
holding down the power button for 10s. However, the "used" column in the
"-/+ buffers/cache:" line stays near 1GB, so that it is clear that
buffers/caches take up almost all the space.
You may wonder why I file this against the kernel and not libreoffice. Well,
I am sure libreoffice is doing something stupid, that could be fixed to
circumvent this problem. But the kernel should simply not allow any user
process to bring down the entire system. Also it seems the kernel is
allocating caches or buffers until it runs out of all memory and then
freezes. If it was only libreoffice allocating memory, OOM killer would kill
it. But nothing like this happens, even if you wait 2h nothing happens. I
think OOM killer does nothing because no single user process uses a lot of
memory. It's the kernel choking on itself.
Ok, so now let me speculate on what might be wrong. I am filing this report
for my laptop that has a i7-3667U CPU with integrated Intel graphics card:
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
But the problem also occurs on 3 other Debian desktop machines that run the
same kernel, and have either Intel or ATI graphics, i.e.:
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Barts PRO [Radeon HD 6850]
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450 / R5 230 OEM]
However, it happens differently on a 4th Debian desktop machine with
07:00.0 VGA compatible controller: NVIDIA Corporation NV42GL [Quadro FX 3450/4000 SDI] (rev a2)
On this one, Gnome3 crashes and dmesg has a lot of lines lines like:
[880754.926611] [TTM] Failed to find memory space for buffer 0xffff880367e42800 eviction
[880754.926613] [TTM] No space for ffff880367e42800 (497 pages, 1988K, 1M)
[880754.926614] [TTM] placement[0]=0x00070002 (1)
[880754.926616] [TTM] has_type: 1
[880754.926617] [TTM] use_type: 1
[880754.926618] [TTM] flags: 0x0000000A
[880754.926619] [TTM] gpu_offset: 0x00000000
[880754.926620] [TTM] size: 131072
[880754.926621] [TTM] available_caching: 0x00070000
[880754.926622] [TTM] default_caching: 0x00010000
This is actually good because after the gnome3 crash the system is still
usable. I should say that in all cases I am using the open source graphics
drivers that use kernel mode setting. So the latter crash leads me to think
that some interaction between the graphics drivers and the kernel leads to
the allocation of too many buffers/caches by the kernel until it runs out.
Probably this is all triggered by libreoffice (running on X) trying to
display some JPG images in a document.
The reason why I consider this security relevant is that anybody with a user
account can use libreoffice to bring the system down. This will cause data
loss since all other users cannot save any data in open files.
Thank you very much for considering this report,
Wolfgang Tichy
