A nasty looking crash is manifesting in various different ways under fuzzing, apparently related to drawing and bitmap handling.
|
|
|
|
A trigger is attached, signal_sigsegv_7ffff5b5aee2_252_0688bbd450e7c095265d00be2fca50ab.swf

The base file from which this fuzz case was generated is attached, 0688bbd450e7c095265d00be2fca50ab.swf

The crash on 64-bit Linux looks like this:
|
|
|
|
=> 0x00007f69314b8f7d: cmpl $0xc,0x174(%rax)
|
|
|
|
rax 0x83071500ff0300 36881008741516032
|
|
|
|
If we trace through the usages of %rax, we can get to some bad writes pretty easily:
|
|
|
|
=> 0x00007f69314b8f7d: cmpl $0xc,0x174(%rax)
|
|
0x00007f69314b8f84: je 0x7f69314b8fa0
|
|
...
|
|
0x00007f69314b8fa0: mov (%rax),%rdi <-- rdi compromised
|
|
0x00007f69314b8fa3: callq 0x7f69314b8810

0x00007f69314b8812: cmp $0x7ffffff,%edx

0x00007f69314b8818: je 0x7f69314b8862

0x00007f69314b8824: sub $0x1,%edx

0x00007f69314b882c: mov 0x14(%rdi),%eax
