2017-04-20build: Make sure plist.pxd is included in tarballsGravatar Christophe Fergeau1-3/+2
When generating a tarball on a system without cython installed, plist.pxd was missing, causing build failures later on when trying to use cython. This seems to be caused by EXTRA_DIST being inside a if HAVE_CYTHON block rather than being outside of it.

2017-04-14Initialize safe_year in time64.cGravatar Greg Dennis1-2/+2
Clang fails with stricter compilation options, because it thinks safe_year may be uninitialized at the return statement. The logic prevents it from being uninitialized, but probably worth the initialization to avoid the compiler error. The rest of libimobiledevice compiles successfully under the same options.
2017-04-06Update time64_limits.hGravatar Greg Dennis1-0/+2
This depends on the 'tm' type being declared, which is defined in time.h.

2017-03-26bplist: Make sure sanity checks work on 32bit platformsGravatar Nikias Bassen1-10/+14
Because on 32-bit platforms 32-bit pointers and 64-bit sizes have been used for the sanity checks of the offset table and object references, the range checks would fail in certain interger-overflowish situations, causing heap buffer overflows or other unwanted behavior. Fixed by wideing the operands in question to 64-bit.

2017-02-15xplist: Improve writing of large PLIST_DATA nodes by growing buffer in advanceGravatar Nikias Bassen4-3/+11
Instead of letting the buffer grow by just the amount of bytes currently transformed to base64 - which is basically line by line - we now calculate the size of the output blob in advance and grow the buffer accordingly. This will reduce the amount of reallocs to just one, which is especially important for large data blobs. While this is a general improvement for all platforms, it is on platforms like Windows where realloc() can be REALLY slow; converting a 20mb blob to XML can easily take up to a minute (due to the several hundred thousand calls to realloc()). With this commit, it will be fast again.
2017-02-10bplist: Fix data range check for string/data/dict/array nodesGravatar Nikias Bassen1-6/+6
Passing a size of 0xFFFFFFFFFFFFFFFF to parse_string_node() might result in a memcpy with a size of -1, leading to undefined behavior. This commit makes sure that the actual node data (which depends on the size) is in the range start_of_object..start_of_object+size. Credit to OSS-Fuzz

This commit adds proper debug/error messages being printed if the binary plist parser encounters anything abnormal. To enable debug logging, libplist must be configured with --enable-debug, and the environment variable PLIST_BIN_DEBUG must be set to "1".

2017-02-04bplist: Fix OOB write on heap buffer and improve recursion checkGravatar Nikias Bassen1-8/+14
Issue #92 pointed out an problem with (invalid) bplist files which have exactly one structured node whose subnode reference itself. The recursion check used a fixed size array with the size of the total number of objects. In this case the number of objects is 1 but the recursion check code wanted to set the node_index for the level 1 which leads to an OOB write on the heap. This commit fixes/improves two things: 1) Prevent OOB write by using a dynamic data storage for the used node indexes (plist_t of type PLIST_ARRAY) 2) Reduces the memory usage of large binary plists, because not the total number of nodes in the binary plist, but the number of recursion levels is important for the recursion check.
2017-02-03bplist: Prevent OOB read when parsing data/string/array/dict size nodesGravatar Nikias Bassen1-0/+2
As reported in #91, the code that will read the big endian integer value of variable size did not check if the actual number of bytes is still withing the range of the actual plist data. This commit fixes the issue with proper bounds checking.
