2017-01-02	xplist: Make sure to error out when encountering empty/incomplete entities	Nikias Bassen	1	-1/+5

2017-01-02	xplist: Make sure to not parse for entities in empty strings	Nikias Bassen	1	-1/+1

2017-01-02	xplist: Allow empty keys in dictionaries	Nikias Bassen	1	-2/+2

2017-01-02	xplist: Allow whitespace after name in closing tag	Nikias Bassen	1	-2/+7
	'</key >' is a perfectly valid closing tag and so is '</key >' (note the newline). This commit will make the parser skip any encountered whitespace before checking for the closing '>'.

2016-12-21	xplist: Fix UaF in code checking for closing tag	Nikias Bassen	1	-2/+2

2016-12-21	xplist: Make sure to correctly parse for closing tags of structured nodes	Nikias Bassen	1	-7/+45

2016-12-21	xplist: Make sure to stop parsing on entity errors	Nikias Bassen	1	-7/+11

2016-12-14	xplist: Remove usage of strlen() wherever possible	Nikias Bassen	1	-45/+66

2016-12-14	xplist: Improve text content parsing, reducing memory usage and unneeded copying	Nikias Bassen	1	-113/+318

2016-12-14	Properly check for the availability of strptime() and make sure to use it	Nikias Bassen	1	-1/+5

2016-11-28	xplist: Fix parsing of adjacent nodes without whitespace between them	Nikias Bassen	1	-2/+1
	The context position counter was increased after encountering a closing node, e.g. '</dict>' or after a closing '</key>' node. When a node followed it directly without any whitespace inbetween, e.g. </dict><key>, parsing would fail since the parser would look at 'key>' instead of '<key>' for the next node to be parsed.
2016-11-13	xplist: Don't parse XML reserved characters in CDATA blocks	Nikias Bassen	1	-0/+1

2016-11-13	xplist: Support converting numerical character entities	Nikias Bassen	1	-3/+51

2016-11-13	xplist: Properly parse CDATA blocks in get_text_content()	Nikias Bassen	1	-7/+23

2016-10-31	xplist: Prevent UaF when parsing structured nodes failstime64	Filippo Bigarella	1	-0/+5
	In case parsing inside `node_from_xml` called from line 842 fails, `data` gets freed by the call to `plist_free` at line 899, since `subnode` is actually created by making it point to `data` at line 684. This commit prevents this situation by bailing out whenever parsing in a deeper level of structured nodes fails.
2016-10-31	xplist: Prevent heap buffer overflow when parsing empty tags	Filippo Bigarella	1	-1/+3
	If `ctx->pos - p - 1` is greater than `taglen`, we end up writing outside the buffer pointed to by `tag`. This commit fixes it by checking the bounds of the heap buffer before writing.
2016-10-31	xplist: Prevent NULL pointer dereference when parsing <real> nodes	Filippo Bigarella	1	-0/+8

2016-10-22	Remove libxml2 dependency in favor of custom XML parsing	Nikias Bassen	1	-350/+652

2016-09-19	Use time64 implementation by Michael G Schwern to extend allowed date/time range	Nikias Bassen	1	-11/+17
	The main benefit of this is to allow date/time values outside of the 32bit time_t range which is very important on 32bit platforms. But there are also some other issues that will be fixed with this, for example on macOS, mktime() will not work for dates < 1902 despite time_t being 64bit. In the same run this commit will also use a reentrant version of gmtime64_r that should help in multithreaded scenarios. Original code taken from: https://github.com/evalEmpire/y2038
2016-09-19	Change internal storage of PLIST_DATE values from struct timeval to double	Nikias Bassen	1	-4/+3
	This removes the timeval union member from the plist_data_t structure. Since struct timeval is 2x64bit on 64bit platforms this member unnecessarily grew the union size to 16 bytes while a size of 8 bytes is sufficient. Also, on 32bit platforms struct timeval is only 2x32bit of size, limiting the range of possible time values. In addition the binary property list format also stores PLIST_DATE nodes as double.
2016-06-29	xplist: Plug memory leak when converting PLIST_UID nodes to XML	Nikias Bassen	1	-0/+1
	In node_to_xml nodes of type PLIST_UID are temporarily converted to a PLIST_DICT for an appropriate XML output. Therefore a PLIST_KEY and a PLIST_UINT node is created and inserted into the PLIST_DICT node. Upon completion, the child nodes of the PLIST_DICT node are detached from the original node and freed, however the data of the child nodes - the key string and the uint value - are not. This commit fixes it.

2015-01-23	xplist: Plug memory leak by cleaning up libxml2's parser after use	Martin Szulecki	1	-0/+16
	This is actually considered bad practice. However, it appears this memory leak is otherwise not possible to fix due to a design flaw in how libxml2 handles the lifecycle of it's XML parser. We'll let the community test this in production now and decide. In our tests this change had no drawbacks except fixing the last known memory leak in libplist.

2015-01-23	xplist: Fix limited but possible XXE security vulnerability with XML plists	Martin Szulecki	1	-4/+16
	By using a specifically crafted XML file an attacker could use plistutil to issue a GET request to an arbitrary URL or disclose a local file. The crafted XML file would be using a custom DTD with an external entity reference pointing to the file. Practical abuse is limited but let's still fix it nevertheless. Related to CVE-2013-0339 for libxml2 and CWE-827. Reported by Loïc Bénis from calypt.com. Thanks!

2012-11-08	Fix crash when converting plists containing comments	Nikias Bassen	1	-0/+4
	Thanks to free2000fly for pointing this out. The issue was that XML plists with comments converted to binary plists would result in invalid binary nodes, thus converting back these binary plists resulted in a crash.
