-----------------------------+----------------------------------------------
Reporter: carlitoburgante | Owner: vadim
Type: defect | Status: new
Priority: major | Milestone: QuteCom 2.2-RC2
Component: 3rd party libs | Version: 2.2-RC3
Keywords: security crash |
-----------------------------+----------------------------------------------
(Build QuteCom 2.2 rev49cd2a2682c9-20081218143907 used)
When sending fuzzed/malformed sip invite messages to the Qutecom client,
several crashes will occur in the following areas:
* phapi.dll:10013924 cmp dl,[ecx] from thread 5840 caused access violation
* phapi.dll:10013917 mov eax,[edx+0x4] from thread 2412 caused access
violation
Below shows the crash areas and test case numbers associated with the
crash

Below are the debug process captures/stack unwinds of test scenarios
(24726, 25529, 25538) and (46, 4449, 4450) in which should help pinpoint
area to resolve.
