crash in OpenSER 1.3.0

Vasanthi Ramasamy



We had crashes in OpenSER 1.3.0 when we  were fuzz testing our voice conference bridges. We are using OpenSER-1.3.0. I have the core dumps and SIP packets we used to fuzz with me, if anybody is interested.


Here is where it had segmentation fault:


Core was generated by `/usr/local/sbin/openser'.

Program terminated with signal 11, Segmentation fault.

Cannot access memory at address 0xb7fd6000

#0  comp_scriptvar (msg=Variable "msg" is not available.

) at route.c:762

762                                                          backup  = s1->s[s1->len];  s1->s[s1->len] = '\0';



Is this something already fixed in recent versions of OpenSER ? if so, which one ?
