Starting in version 0.3.0 and prior to version 1.0.0-alpha-1, a nil pointer dereference vulnerability is in the SIPGO library's `NewResponseFromRequest` function that affects all normal SIP operations. The vulnerability allows remote attackers to crash any SIP application by sending a single malformed SIP request without a To header. The vulnerability occurs when SIP message parsing succeeds for a request missing the To header, but the response creation code assumes the To header exists without proper nil checks. This affects routine operations like call setup, authentication, and message handling - not just error cases. This vulnerability affects all SIP applications using the sipgo library, not just specific configurations or edge cases, as long as they make use of the `NewResponseFromRequest` function. Version 1.0.0-alpha-1 contains a patch for the issue.","affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/emiago/sipgo","events":[{"introduced":"6ffeb52b05766d9a39dfe23b08bfd07029d79dfe"},{"fixed":"ae239324512644ea045cb19b3bc1deb3871476cd"},{"fixed":"dc9669364a154ec6d134e542f6a63c31b5afe6e8"}],"database_specific":{"cpe":"cpe:2.3:a:emiago:sipgo:*:*:*:*:*:go:*:*","extracted_events":[{"introduced":"0.30.0"},{"fixed":"1.0.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v1.0.0-beta-4","v1.0.0-beta-3","v1.0.0-beta-2","v1.0.0-beta-1","v1.0.0-alpha-2","v1.0.1-alpha","v1.0.0-alpha-1","v1.0.0-alpha","v0.33.0","v0.32.1","v0.32.0","v0.31.0","v0.30.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68274.json"}}],"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68274.json"},{"type":"ADVISORY","url":"https://github.com/emiago/sipgo/security/advisories/GHSA-c623-f998-8hhv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68274"},{"type":"FIX","url":"https://github.com/emiago/sipgo/commit/dc9669364a154ec6d134e542f6a63c31b5afe6e8"}],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-476","CWE-755"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68274.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
