+Subject: [PATCH 03/40] Avoid use-after-free in dix/dixfonts.c: doImageText()
+ [CVE-2013-4396] from 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.

+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.

+Subject: [PATCH 06/40] CVE-2014-0209: integer overflow of realloc() size in
+ lexAlias() from 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.

+
+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.

+Subject: [PATCH 10/40] CVE-2014-0211: Integer overflow in
+ fs_get_reply/_fs_start_read from 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.

+Subject: [PATCH 11/40] CVE-2014-0210: unvalidated length fields in
+ fs_read_query_info() from 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.

+fs_read_extent_info() parses a reply from the font server.
+The reply contains a 32bit number of elements field which is used
+to calculate a buffer length. There is an integer overflow in this
+calculation which can lead to memory corruption.

+Subject: [PATCH 18/40] unchecked malloc may allow unauthed client to crash
+ Xserver [CVE-2014-8091]
+
+authdes_ezdecode() calls malloc() using a length provided by the
+connection handshake sent by a newly connected client in order
+to authenticate to the server, so should be treated as untrusted.
+
+It didn't check if malloc() failed before writing to the newly
+allocated buffer, so could lead to a server crash if the server
+fails to allocate memory (up to UINT16_MAX bytes, since the len
+field is a CARD16 in the X protocol).

+ProcPutImage() calculates a length field from a width, left pad and depth

+
+The calculations for the total amount of memory the server needs for the
+pixmap can overflow a 32-bit number, causing out-of-bounds memory writes
+on 32-bit systems (since the length is stored in a long int variable).

+Subject: [PATCH 20/40] dix: integer overflow in GetHosts() [CVE-2014-8092 2/4]
+
+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.
+
+This patch caps the list at 1mb, because multi-megabyte hostname
+lists for X access control are insane.

+Subject: [PATCH 23/40] dbe: unvalidated lengths in DbeSwapBuffers calls
+ [CVE-2014-8097]
+
+ProcDbeSwapBuffers() has a 32bit (n) length value that it uses to read
+from a buffer. The length is never validated, which can lead to out of
+bound reads, and possibly returning the data read from out of bounds to
+the misbehaving client via an X Error packet.
+
+SProcDbeSwapBuffers() swaps data (for correct endianness) before
+handing it off to the real proc.  While doing the swapping, the
+length field is not validated, which can cause memory corruption.
+
+v2: reorder checks to avoid compilers optimizing out checks for overflow
+that happen after we'd already have done the overflowing multiplications.
+v3: backport to nx-libs 3.6.x (Mike DePaulo)

+Subject: [PATCH 24/40] Xi: unvalidated lengths in Xinput extension
+ [CVE-2014-8095]
+
+Multiple functions in the Xinput extension handling of requests from
+clients failed to check that the length of the request sent by the
+client was large enough to perform all the required operations and
+thus could read or write to memory outside the bounds of the request
+buffer.
+
+This commit includes the creation of a new REQUEST_AT_LEAST_EXTRA_SIZE
+macro in include/dix.h for the common case of needing to ensure a
+request is large enough to include both the request itself and a
+minimum amount of extra data following the request header.

+Subject: [PATCH 31/40] glx: Be more paranoid about variable-length requests
+ [CVE-2014-8093 1/6] (v2)
+
+If the size computation routine returns -1 we should just reject the
+request outright.  Clamping it to zero could give an attacker the
+opportunity to also mangle cmdlen in such a way that the subsequent
+length check passes, and the request would get executed, thus passing
+data we wanted to reject to the renderer.

+ [CVE-2014-8093 2/6]
+
+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.

+Subject: [PATCH 34/40] glx: Add safe_{add,mul,pad} (v3) [CVE-2014-8093 4/6]
+ (v4)
+
+These are paranoid about integer overflow, and will return -1 if their
+operation would overflow a (signed) integer or if either argument is
+negative.
+
+Note that RenderLarge requests are sized with a uint32_t so in principle
+this could be sketchy there, but dix limits bigreqs to 128M so you
+shouldn't ever notice, and honestly if you're sending more than 2G of
+rendering commands you're already doing something very wrong.
+
+v2: Use INT_MAX for consistency with the rest of the server (jcristau)
+v3: Reject negative arguments (anholt)
+
+v4: RHEL5: add limits.h, use inline
+
+v5: backport to nx-libs 3.6.x (Mike DePaulo)

+Subject: [PATCH 39/40] glx: Length checking for RenderLarge requests (v2)
+ [CVE-2014-8098 3/8] (v3)
+
+This is a half-measure until we start passing request length into the
+varsize function, but it's better than the nothing we had before.
+
+v2: Verify that there's at least a large render header's worth of
+dataBytes (Julien Cristau)
+
+v3: backport to RHEL5
+
+v4: backport to nx-libs 3.6.x (Mike DePaulo)
