kamailio: CVE-2018-14767

Severity: Medium
Published: Jul 31, 2018, 6:29:00 AM UTC
Source: [NVD] · [CVE record]
EPSS: 29.30% · Oct 25, 2026

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.
