In libosip2 in GNU oSIP 4.1.0, a malformed SIP message can lead to a heap buffer overflow in the osip_clrncpy() function defined in osipparser2/osip_port.c.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
