|
There is a heap overflow in daeElement::setElementName(). The
|
|
vulnerable method uses a fixed size (128 bytes) heap-allocated buffer to
|
|
copy the name of an arbitrary element. By setting the name of the element
|
|
to something larger the buffer is overflown.
|
|
|
|
The vulnerable code does something like this:
|
|
if (element_name) {
|
|
if (!this->name) {
|
|
this->name = new char[128];
|
|
}
|
|
strcpy(this->name, element_name);
|
|
}
|
|
|
|
The element_name is supplied by the user and can be more than 128
|
|
characters long.
|
|
|
|
Steps to reproduce (Note: you need to enable libgmalloc):
|
|
a) $ lldb
|
|
b) (lldb) target create /usr/bin/qlmanage
|
|
Current executable set to '/usr/bin/qlmanage' (x86_64).
|
|
c) (lldb) env DYLD_INSERT_LIBRARIES=/usr/lib/libgmalloc.dylib
|
|
d) (lldb) process launch -- -p setElementNameOOB.dae
|
|

This bug has been tested on:
|
|
$ sw_vers
|
|
ProductName: Mac OS X
|
|
ProductVersion: 10.10.3
|
|
BuildVersion: 14D136
|
|
|
|
$ qlmanage --version
|
|
QuickLook framework: v5.0 (675.42)
|
|
|
|
Attached are two files:
|
|
1) setElementNameOOB.dae - the POC dae file.
|
|
2) setElementNameOOB_dae.crashlog.txt - the CrashWrangler log.
|
|
|
|
Attack vector:
|
|
This bug can be triggered by any application that uses the QuickLook framework to generate a preview/thumbnail of DAE (COLLADA) files. For example, loading the supplied POC in Preview or selecting the file in Finder and hitting <space> will trigger the bug.
