Just similar to commit [7fed314](https://github.com/libming/libming/commit/7fed314748be817c7ded84854acb649786625cb6),in func parseSWF_DEFINESPRITE (util/parser.c) ,splength(line 2302) has intint type but according to the specification it should be able to store unsigned 32bit numbers. There should be a check to verify that the value returned by readUInt32 is smaller than INT_MAX and update splength if it's the case.Otherwise we should print a warning and ignore the block.

] | Hi there.
It seems there are potential memory leak in parserSWF_MORPHFILLSTYLES (parser.c:827) and parseSWF_SHAPE (parser.c:845) on the newest master branch 04aee52363688426eab74f5d618.
<img width="1009" alt="image" src="https://user-images.githubusercontent.com/7632714/91017887-6588e100-e621-11ea-8868-20d1c6ea7b4c.png">
The memory allocated for FillSystyles is not freed after the program ends.
A similar issue happens in the function parseSWF_SHAPE.
These allocation sizes are accessible for the user and thus may lead to a huge amount of memory leak in frequent file transformation on the server.
This is the demo example and the traces reproducible on the master branch.

```
Set breakpoint before calling ``println()``. ``decompileGETURL()`` received a structure pointer parameter ``SWF_ACTION *act``. However, the heap chunk was overflowed by input. So the member pointers can be controlled by crafted input data:
```
gdb> p sact->UrlString
$1 = (STRING) 0x8383838383838383 <error: Cannot access memory at address 0x8383838383838383>
gdb> p sact->TargetString
$2 = (STRING) 0x8383838383838383 <error: Cannot access memory at address 0x8383838383838383>
```
As the pointers are then dereferenced in ``println("getUrl('%s',%s);"...``, it may result in an Information Disclosure and potentially Code Execution.
This problem exists in the released 0.4.8 and the latest commit ``5009802``.

In fact, this is a similar bug with [#187](https://github.com/libming/libming/issues/187).
A heap address with content 0 from ``pop()`` was passede to ``getName()``, and ``getName()`` just return 0.Then the return value was passed to ``strlen()`` without any checks.

```C
v->p.String = malloc(strlen(var)+strlen(var2)+strlen(var3)+strlen(var4)+strlen(var5)+1);
```
More specifically, ``decompileGETPROPERTY()`` passed a heap address with content 0 to ``getName()``, and ``getName()`` just return 0. However, ``decompileGETPROPERTY()`` didn't check the return value of ``getName()`` and directly passed it to ``newVar5()``. So a null pointer is passed to ``newVar5()``, then passed to ``strlen()``, whose return value is a parameter of ``malloc()``
This should be caused by the improper way of patching 8dd118e. ``getName()`` returns null to handle errors. But the return value was not checked properly where it was called, resulting in another null pointer reference.

] | Building and using the python extension with python3 fails. Apart from fixing detection in `configure` ([macros/python.m4](https://github.com/libming/libming/blob/master/macros/python.m4)), it's also necessary to port ([py_ext/ming.py](https://github.com/libming/libming/blob/master/py_ext/ming.py)) to python3 (`2to3` works fairly well, but doesn't fix whitespace inconsistencies). However, that's still not enough. Apparently, the [SWIG bindings](https://github.com/libming/libming/blob/master/ming.i#L15) use python2-only APIs like `PyFile_Check` and `PyFile_AsFile`, which are not available in python3.

Because regs[actions[n+1].SWF_ACTIONSTOREREGISTER.Register] is null, there exists a null pointer dereference when accessing regs[actions[n+1].SWF_ACTIONSTOREREGISTER.Register]->Type.

"libming",
"libming"
] | Hi, there.
A Heap-buffer-overflow problem was discovered in decompileJUMP function in util/decompile.c of libming v0.4.8. This problem can be reproduced in the latest code base, too. A crafted input can cause segment faults and I have confirmed them with address sanitizer too.
Here is the POC file. Please use the "./swftocxx $POC /dev/null" to reproduce the bug.

The ASAN dumps the stack trace as follows:

```
Previous versions of Autoconf promoted the name configure.in, which is somewhat ambiguous (the
tool needed to process this file is not described by its extension), and introduces a slight confusion
with config.h.in and so on (for which ‘.in’ means “to be processed by configure”). Using configure.ac is
now preferred.

] | Hey there, I have come across some integer behaviour runtime issues in the commit 50e2bf750fd857edc86dc06a0c615dbe5a166d71.
The shift operations left-shift an integer outside the number of bits supported by the data type, and is an undefined behavior in C according to ISO C99.
The unsigned integer overflow could cause undefined behaviour in the runtime of the software.
To replicate, I compiled the git repo with:
`CC=clang CXX=clang++ CFLAGS='-fsanitize=address,undefined -g -O2 -fPIC -DSWF_LITTLE_ENDIAN' CXXFLAGS=$CFLAGS ./configure; make`
The issues reported by UBSan are as follows:
```
- read.c:71:11: runtime error: left shift of 310079501 by 8 places cannot be represented in type 'int'
- read.c:90:11: runtime error: left shift of 2032175751 by 5 places cannot be represented in type 'int'
- read.c:111:20: runtime error: left shift of 1 by 31 places cannot be represented in type 'int'

] | In latest version of libming (0.4.8), there is a heap-use-after-free in decompileJUMP function of decompile.c file, which could be triggered by the POC below.
The "FREE" operation corresponds to a "realloc" in parseSWF_DOACTION (parser.c:2435):
2424 SWF_Parserstruct *
2425 parseSWF_DOACTION (FILE * f, int length)
2426 {
2433 while ( fileOffset < end ) {
2434 parseSWF_ACTIONRECORD (f, &(parserrec->numActions), parserrec->Actions );
2435 parserrec->Actions = (SWF_ACTION *) **realloc** (parserrec->Actions,
…
2441 }
…
2446 }
The freed memory is used in decompileJUMP function (decompile.c:1857):
1810 static int
1811 decompileJUMP(int n, SWF_ACTION *actions, int maxn)
1812 {
...
1857 if (sactif->**Actions**[sactif->numActions-1].SWF_ACTIONRECORD.ActionCode==SWFACTION_JUMP
...
1922 }
To reproduce the issue, compile libming with ASAN and run: ./swftophp $POC

] | In the parseSWF_ACTIONRECORD function (util/parser.c), in the case of `SWFACTION_PUSH`, we enter in a loop which always allocates memory for the next element at the end of the current round:
```
case SWFACTION_PUSH:
{
(snip)
struct SWF_ACTIONPUSHPARAM *param;
(snip)
end = fileOffset + act->Length;
act->Params = (struct SWF_ACTIONPUSHPARAM *) calloc (1, sizeof (struct SWF_ACTIONPUSHPARAM)); <-- Allocate memory for the first element
act->NumParam = 0;
while ( fileOffset < end ) {
param = &(act->Params[act->NumParam++]);
param->Type = readUInt8(f);
switch( param->Type ) {
case 0: /* STRING */
param->p.String = readString(f);
break;
(snip)
case 9: /* CONSTANT16 */
param->p.Constant16 = readUInt16(f);
break;
default:
printf("Unknown data type to push %x\n", param->Type );
exit(1);
}
act->Params = (struct SWF_ACTIONPUSHPARAM *) realloc (act->Params,
(act->NumParam + 1) *
sizeof (struct SWF_ACTIONPUSHPARAM)); <-- Allocate memory for the next element
}
break;
}
```
It looks like we are always allocating an element 'too far', wasting 32 bytes. This type of mistake can be seen at other places in the source code. | Memory waste in parseSWF_ACTIONRECORD (util/parser.c) | https://api.github.com/repos/libming/libming/issues/126/comments | 0 | 2018-03-14T20:55:47Z | 2018-03-14T20:55:47Z | https://github.com/libming/libming/issues/126 | 305,325,235 | 126 |
