| | | | | | | | | | | | | | | | | | Before this we'd just clamp the image size to 0, which was just hideously stupid; if the parameters were such that they'd overflow an integer, you'd allocate a small buffer, then pass huge values into (say) ReadPixels, and now you're scribbling over arbitrary server memory. v2: backport to nx-libs 3.6.x (Mike DePaulo) Reviewed-by: Keith Packard <keithp@keithp.com> Reviewed-by: Julien Cristau <jcristau@debian.org> Reviewed-by: Michal Srb <msrb@suse.com> Reviewed-by: Andy Ritger <aritger@nvidia.com> Signed-off-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Signed-off-by: Fedora X Ninjas <x@fedoraproject.org> Signed-off-by: Dave Airlie <airlied@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | ProcDbeSwapBuffers() has a 32bit (n) length value that it uses to read from a buffer.

| | | | | | | | | | | | | | | | | | | | GetHosts() iterates over all the hosts it has in memory, and copies them to a buffer. The buffer length is calculated by iterating over all the hosts and adding up all of their combined length. There is a potential integer overflow, if there are lots and lots of hosts (with a combined length of > ~4 gig). This should be possible by repeatedly calling ProcChangeHosts() on 64bit machines with enough memory.

* CVE-2014-0211: Integer overflow in fs_get_reply/_fs_start_read from ↵Mike DePaulo2015-02-141-0/+18
| | | | | | | | | | | | | | | | | | | | xorg/lib/libXfont commit 0f1a5d372c143f91a602bdf10c917d7eabaee09b fs_get_reply() would take any reply size, multiply it by 4 and pass to _fs_start_read. If that size was bigger than the current reply buffer size, _fs_start_read would add it to the existing buffer size plus the buffer size increment constant and realloc the buffer to that result. This math could overflow, causing the code to allocate a smaller buffer than the amount it was about to read into that buffer from the network. It could also succeed, allowing the remote font server to cause massive allocations in the X server, possibly using up all the address space in a 32-bit X server, allowing the triggering of other bugs in code that fails to handle malloc failure properly. This patch protects against both problems, by disconnecting any font server trying to feed us more than (the somewhat arbitrary) 64 mb in a single reply.

The reply specifies a total size of all the font server names, and then provides a list of names. _fs_recv_conn_setup() allocated the specified total size for copying the names to, but didn't check to make sure it wasn't copying more data to that buffer than the size it had allocated.
* CVE-2014-0209: integer overflow of realloc() size in lexAlias() from ↵Mike DePaulo2015-02-141-0/+4
| | | | | | | | | | | | | | | xorg/lib/libXfont commit 05c8020a49416dd8b7510cbba45ce4f3fc81a7dc lexAlias() reads from a file in a loop. It does this by starting with a 64 byte buffer. If that size limit is hit, it does a realloc of the buffer size << 1, basically doubling the needed length every time the length limit is hit. Eventually, this will shift out to 0 (for a length of ~4gig), and that length will be passed on to realloc(). A length of 0 (with a valid pointer) causes realloc to free the buffer on most POSIX platforms, but the caller will still have a pointer to it, leading to use after free issues.
* CVE-2014-0209: integer overflow of realloc() size in FontFileAddEntry() from ↵Mike DePaulo2015-02-141-0/+5
| | | | | | | | | | | | | | | xorg/lib/libXfont commit 2f5e57317339c526e6eaee1010b0e2ab8089c42e FontFileReadDirectory() opens a fonts.dir file, and reads over every line in an fscanf loop. For each successful entry read (font name, file name) a call is made to FontFileAddFontFile(). FontFileAddFontFile() will add a font file entry (for the font name and file) each time it’s called, by calling FontFileAddEntry(). FontFileAddEntry() will do the actual adding. If the table it has to add to is full, it will do a realloc, adding 100 more entries to the table size without checking to see if that will overflow the int used to store the size.

If we hit an error, once we free(c), reset c to point to the original structure before jumping to the cleanup code that references *c. Since one of the errors being checked for is whether the server was able to malloc(c->nChars * itemSize), the client can potentially pass a number of characters chosen to cause the malloc to fail and the error path to be taken, resulting in the read from freed memory. Since the memory is accessed almost immediately afterwards, and the X server is mostly single threaded, the odds of the free memory having invalid contents are low with most malloc implementations when not using memory debugging features, but some allocators will definitely overwrite the memory there, leading to a likely crash.

* Do not build bundled libraries ↵Orion Poplawski2015-02-133-11/+14
| | | | | | | | | | | | (601_nx-X11_build-option-changes-to-not-use-bundled-libraries.full.patch). This commit has been submitted by Orion in two portions. One was submitted to X2Go BTS and created on Wed, 10 Jul 2013. The other portion has been taken from the Fedora package by Mike Gabriel and worked into this patch on Fri, 06 Dec 2013.
* Unique Library Names Patch ↵Jan Engelhardt2015-02-1328-168/+168
| | | | | | | | | | | | | | | | | | | | (600_nx-X11+nxcompext+nxcompshad_unique-libnames.full.patch). We really want to make use of rpm's automatic dependency finding. Binaries are scanned for DT_NEEDED entries, the latter of which are then used for populating the "Requires"-type deps. The "nxagent" binary for example would require libX11.so.6. That incurs problems: 1. A package manager told to install nxagent could select xorg-x11 rather than nx-libs, even though nxagent depends on the NX version. 2. A package manager told to install $some_program could select nx-libs rather than xorg-x11 (since both provide libX11.so.6), but, since the NX library is in an obscure directory, running $some_program would fail as libX11.so.6 is not found. To solve this, give the NX libraries unique names different from the Xorg ones.
* Adapt paths of keystrokes.cfg if nxagent runs as x2goagent ↵Horst Schirmeier2015-02-131-0/+6
| | | | (321_nxagent_x2go-specific-keystroke-config.full.patch).
* Make nxagent-specific keyboard bindings configurable ↵Alexander Wuerstlein2015-02-136-237/+546
| | | | | | | | | | | | | | (320_nxagent_configurable-keystrokes.full.patch). Replaces the hardcoded nxagent keybindings by a configurable table of keybindings. The default configuration is the same as the original one, to maintain compatibility. A user/administrator can either specify a command line parameter, environment variable or place a file in ~/.nx/config/keystrokes.cfg or /etc/nxagent/keystrokes.cfg to reconfigure these keybindings. The configuration file format is XML, a dependency on libxml2 is added to allow parsing the configuration.
* Test for xkb/rules/base instead of xkb/keymap.dir for setting XkbBaseDir ↵Mike Gabriel2015-02-131-16/+16
| | | | | | | | (302_nx-X11_xkbbasedir-detection.full.patch). In recent (as of 2014/06) X.org release, the keymap.dir file has become obsolete. Let's test for the xkb/rules/base file instead.
* Use shared libraries (301_nx-X11_use-shared-libs.full.patch).Jan Engelhardt2015-02-103-9/+10
| | | | | | | | | | | | Many distributions have a policy to reduce code duplications. One means to avoid such duplications is to use shared libraries instead of using libs that are ofter shipped for convenience. Fedora: http://fedoraproject.org/wiki/Packaging:Guidelines#Shared_Libraries Debian (Section 10.7.4 of Debian policy): http://www.debian.org/doc/debian-policy/ch-files.html
* Set WM_CLASS to X2GoAgent/NXAgent (300_nxagent_set-wm-class.full.patch).Oleksandr Shneyder2015-02-101-0/+36
| | | | | | | | | | | | | | Depending on the binary name of the agent either NXAgent or X2GoAgent is set as WM_Class. This is needed for some window managers (like the one shipped with Maemo) The original WM_CLASS patch has been taken from the FreeNX patch series, author unknown. The nxagent/x2goagent has been done by the X2Go Project, author see below.
* Save session state in file.Oleksandr Shneyder2015-02-105-1/+51
| | | | | | | | | 210_nxagent_save_session_state.full.patch 210_nxcomp_save_session_state.full+lite.patch This patch adds a "state" option to NX (agent) which allows one to specify a file where nxagent will write its session state into.
