                                                                      A vulnerability has been reported in WhatsApp which could be exploited by a remote attacker to execute arbitrary code on the affected system.
                                                                      
										
								       Description 
										
 
                                            This vulnerability exists in WhatsApp due to a buffer overflow condition error. A remote attacker could exploit this vulnerability by making a decoy Whatsapp voice call to a target user¿s phone number and thereby sending specially crafted series of SRTCP packets to the target system. This could trigger a buffer overflow condition leading to execution of arbitrary code by the attacker.
                                           
                                            
                                            
                                            	
                                            
                                           
										   
										  	  	 Successful exploitation of this vulnerability could allow the attacker to access information on the system such as call logs, messages, photos, etc which could lead to further compromise of the system.
