2022-11-02jplist: Prevent multiplication overflow by casting to larger typeGravatar Nikias Bassen1-2/+2

2022-09-05Get rid of casting a ptr to a 32 bit valueGravatar Dave MacLachlan1-2/+2
This causes a warning if `-Wbad-function-cast` is enabled on a build.
2022-08-24bplist: Fix strict aliasing violationsGravatar Matthew Smith1-3/+9
Casting a float pointer to an int pointer is a strict aliasing violation (-Wstrict-aliasing) and is undefined behaviour (although, it did not seem to cause any real issues). An optimising compiler should elide the memcopies added by this commit.

2022-02-02jplist: Improve numerical value parsing without copying data to stack bufferGravatar Nikias Bassen1-18/+62
Instead of calling strtoll() and atof(), the code now parses the numerical values directly to handle cases of non-0-terminated string data. The floating point value parsing is probably not ideal, but sufficient for our purposes.

2022-01-31jplist: Fix OOB read in parse_primitive caused by missing 0-terminationGravatar Nikias Bassen1-2/+8
In parse_primitive, integer and double values are parsed by using strtoll and atof, which both expect the string to be 0-terminated. While this is not a problem in well-formed JSON files, it can be if the JSON data is not, possibly leading to a crash due to OOB memory access. This commit fixes it by copying the value data in question to a stack buffer and 0-terminate it, and use that buffer instead. Credit to OSS-Fuzz

This way the string doesn't have to be 0-terminated.

2021-12-23xplist: Add special handling for PLIST_UID parsing from XMLGravatar Nikias Bassen1-5/+14
In XML, PLIST_UID nodes are stored as a dict with a "CF$UID" key and an integer value, so we want to make it a real PLIST_UID node internally.
2021-12-22Add a return value to plist_to_* and plist_from_* functionsGravatar Nikias Bassen3-38/+101
This way it can be easier determined why an import/export operation failed instead of just having a NULL result.

2021-12-19Add new plist_mem_free() functionGravatar Nikias Bassen3-10/+8
Thanks to @azerg for bringing this to my attention. Instead of having multiple (internally identical) plist_*_free() functions, this commit introduces a single plist_mem_free() that can be used to free the memory allocated by plist_to_xml(), plist_to_bin(), plist_get_key_val(), plist_get_string_val(), and plist_get_data_val(). Note: This commit REMOVES plist_to_bin_free() and plist_to_xml_free().

2021-07-13cpp: Array: Make sure the array passed to array_fill ist passed by referenceGravatar liujianfengv1-1/+1
When creating a new Array object, for example through PList::Node::FromPlist(plist_t node), the array_fill function is called from Array() constructor in line 51. It seems that the intended way of calling array_fill() is to pass the _array object by reference, however it is actually passed by value. Thus the changes to the array object made by array_fill() are discarded when the function returns. This commit passes the _array by reference so we keep the changes.

2021-06-22[clang-tidy] Remove pointless constGravatar Rosen Penev2-2/+2
