* CVE-2014-0210: unvalidated length fields in fs_read_query_info() from ↵Mike DePaulo2015-02-142-7/+52
| | | | | | | | | xorg/lib/libXfont commit 491291cabf78efdeec8f18b09e14726a9030cc8f fs_read_query_info() parses a reply from the font server. The reply contains embedded length fields, none of which are validated. This can cause out of bound reads in either fs_read_query_info() or in _fs_convert_props() which it calls to parse the fsPropInfo in the reply.
* 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.
* CVE-2014-0210: unvalidated lengths when reading replies from font server ↵Mike DePaulo2015-02-141-6/+38
| | | | | | | | from xorg/lib/libXfont commit cbb64aef35960b2882be721f4b8fbaa0fb649d12 Functions to handle replies to font server requests were casting replies from the generic form to reply specific structs without first checking that the reply was at least as long as the struct being cast to.

* CVE-2014-0210: unvalidated length in _fs_recv_conn_setup() from ↵Mike DePaulo2015-02-141-3/+18
| | | | | | | | | | | | | xorg/lib/libXfont commit 891e084b26837162b12f841060086a105edde86d The connection setup reply from the font server can include a list of alternate servers to contact if this font server stops working. 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.
* CVE-2013-6462: unlimited sscanf overflows stack buffer in ↵Mike DePaulo2015-02-141-1/+1
| | | | | | | | bdfReadCharacters() from xorg/lib/libXfont http://lists.x.org/archives/xorg-announce/2014-January/002389.html Fixes cppcheck warning: [lib/libXfont/src/bitmap/bdfread.c:341]: (warning) scanf without field width limits can crash with huge input data.
* Avoid use-after-free in dix/dixfonts.c: doImageText() [CVE-2013-4396] from ↵Mike DePaulo2015-02-141-0/+5
| | | | | | | | | | | | | | | | | | | | | xorg/Xserver http://lists.x.org/archives/xorg-announce/2013-October/002332.html Save a pointer to the passed in closure structure before copying it and overwriting the *c pointer to point to our copy instead of the original. 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.
* Fix CVE-2011-4028: File disclosure vulnerability. upstream xorg/xserver ↵Mike DePaulo2015-02-141-1/+1

* Prepare for maintaing upstream changes in upstream ChangeLog.Mike Gabriel2015-02-144-24/+4
| | | | | | | | | | | | | | | | This makes it obsolete to add changes to debian/changelog. We document our changes in Git (3.6.x branch and other related branches). On release, we generate an upstream ChangeLog from Git history. Only on the 3.5.0.x, we continue maintaining our changes in debian/changelog (to be compliant with current nx-libs release workflow in X2Go). The following packaging scripts needed adaptations to this change: debian/roll-tarballs.sh debian/rules nx-libs.spec

* Unbrand NX Agent Startup Screen / Brand X2Go Agent Startup Screen ↵Oleksandr Shneyder2015-02-137-445/+158
| | | | | | | | | | (999_nxagent_unbrand-nxagent-brand-x2goagent.full.patch). When launched with NX Agent flavour, the startup screen gets unbranded by this patch (the !M logo does not get shown). When launched with X2Go Agent flavour, the startup screen gets branded with the X2GO logo.

* Several fixes for building debug versions of NX ↵Mihai Moldovan2015-02-136-77/+8
| | | | | | | | | | | | | | | | | | (990_fix-DEBUG-and-TEST-builds.full.patch). (1) In nx-X11/programs/Xserver/dix: Fix several compile errors when specifying -DDEBUG globally. Previous GCC versions were more liberal and the code thus compiled. Also initialize/reset a count variable correctly. (2) In nx-X11/programs/Xserver/hw/nxagent/Render.c: Check for pSrc->pDrawable to exist instead of having nxagent segfault when it does not. This enables the possibility of compiling all nxagent modules in TEST mode.

* In Types.h, don't use STL internals on libc++ ↵Clemens Lang2015-02-133-53/+8
| | | | | | | | | | | | | | | | | (605_nxcomp_Types.h-dont-use-STL-internals-on-libc++.full+lite.patch). The nx-libs-lite package does not compile on OS X Mavericks because Apple's clang compilers now default to compiling against the libc++ STL rather than (their outdated copy of) libstdc++. While the compiler still allows changing that, we should not rely on this being possible forever. The compiler chokes in Types.h, specifically the clear() methods in subclasses of vectors that use implementation details of the GNU STL. The attached patch fixes these compilation issues by not overriding the clear() method when compiling against libc++, since the libc++ headers seem to do essentially the same as the overriden method.
* Handle some serious compilation warnings ↵Mirraz Mirraz2015-02-135-41/+7
| | | | (603_nx-X11_compilation_warnings.full.patch).
* Be compliant with POS36-C: Observe correct revocation order while ↵Orion Poplawski2015-02-134-68/+10
| | | | | | | | | | | | | | | | relinquishing privileges (602_nx-X11_initgroups.full.patch). The Fedora review of NX (redistributed) caught the following rpmlint issue: This executable is calling setuid and setgid without setgroups or initgroups. There is a high probability this mean it didn't relinquish all groups, and this would be a potential security issue to be fixed. Seek POS36-C on the web for details about the problem. Ref POS36-C: https://www.securecoding.cert.org/confluence/display/seccode/POS36-C.+Observe+correct+revocation+order+while+relinquishing+privileges This patch adds initgroups() calls to the code to initialize the supplemental group list.
* Do not build bundled libraries ↵Orion Poplawski2015-02-135-111/+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 Engelhardt2015-02-1332-1356/+172
| | | | | | | | | | | | | | | | | | | | (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.

* Make nxagent-specific keyboard bindings configurable ↵Alexander Wuerstlein2015-02-138-1269/+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 Gabriel2015-02-133-101/+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.

| | | | | | | | | | | | 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.
