* include: introduce byte counting functions.Peter Hutterer2015-02-171-0/+30
| | | | | | | | | | | | | | | | | | | | This patch adds the following three functions: bits_to_bytes(bits) - the number of bytes needed to hold 'bits' bytes_to_int32(bytes) - the number of 4-byte units to hold 'bytes' pad_to_int32(bytes) - the closest multiple of 4 equal to or larger than 'bytes'. All three operations are common in protocol processing and currently the server has ((foo + 7)/8 + 3)/4 operations all over the place. A common set of functions reduce the error rate of these (albeit simple) calculations and improve readability of the code. The functions do not check for overflow. v2: backport to nx-libs 3.6.x as a prereq for the CVE-2015-0255 fix (Mike DePaulo) Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
* Xi: unvalidated lengths in Xinput extension [CVE-2014-8095]Alan Coopersmith2015-02-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. v2: backport to nx-libs 3.6.x (Mike DePaulo) Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Conflicts: Xi/chgdctl.c Xi/chgfctl.c Xi/xiallowev.c Xi/xichangecursor.c Xi/xichangehierarchy.c Xi/xigetclientpointer.c Xi/xigrabdev.c Xi/xipassivegrab.c Xi/xiproperty.c Xi/xiquerydevice.c Xi/xiquerypointer.c Xi/xiselectev.c Xi/xisetclientpointer.c Xi/xisetdevfocus.c Xi/xiwarppointer.c [RHEL5: Xi/xi* files are XI2 ]

| | | | | | | | | | | | | | | | | | RegionSizeof contains several integer overflows if a large length value is passed in.
