CWE-20

Description

In Kamailio before 5.0.7 and 5.1.x before 5.1.4, a crafted SIP message with a double "To" header and an empty "To" tag causes a segmentation fault and crash. The reason is missing input validation in the "build_res_buf_from_sip_req" core function. This could result in denial of service and potentially the execution of arbitrary code.

Affected configurations

• debian debian linux 8.0 • debian debian linux 9.0 • kamailio kamailio (< 5.0.7) • kamailio kamailio (>= 5.1.0 < 5.1.4)
