Once UPF receives a request, it gets the f_teid_len from incoming message, and then uses it to copy data from incoming message to struct f_teid without checking the maximum length. If the pdi.local_f_teid.len exceeds the maximum length of the struct of f_teid, the memcpy() overwrites the fields (e.g., f_teid_len) after f_teid in the pdr struct. After parsing the request, the UPF starts to build a response. The f_teid_len with its overwritten value is used as a length for memcpy(). A segmentation fault occurs, as a result of a memcpy(), if this overwritten value is large enough.","state":"PUBLIC","assigner":"disclosure@synopsys.com","published_at":"2022-09-16 19:15:00","updated_at":"2022-09-21 14:27:00"},"problem_types":["NVD-CWE-noinfo"],"metrics":[],"references":[{"url":"https://www.synopsys.com/blogs/software-security/cyrc-advisory-open5gs/","name":"https://www.synopsys.com/blogs/software-security/cyrc-advisory-open5gs/","refsource":"MISC","tags":[],"title":"CyRC Vulnerability Advisory: Denial-of-service vulnerabilities (CVE-2022-39063) in Open5GS | Synopsys","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-39063","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39063","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"39063","vulnerable":"1","versionEndIncluding":"2.4.9","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"open5gs","cpe5":"open5gs","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"data_type":"CVE","data_format":"MITRE","data_version":"4.0","CVE_data_meta":{"ID":"CVE-2022-39063","ASSIGNER":"disclosure@synopsys.com","STATE":"PUBLIC"},"affects":{"vendor":{"vendor_data":[{"vendor_name":"Open5GS","product":{"product_data":[{"product_name":"Open5GS","version":{"version_data":[{"version_value":"<2.4.9"}]}}]}}]}},"problemtype":{"problemtype_data":[{"description":[{"lang":"eng","value":"CWE-676: Use of Potentially Dangerous Function"}]}]},"references":{"reference_data":[{"url":"https://www.synopsys.com/blogs/software-security/cyrc-advisory-open5gs/","refsource":"MISC","name":"https://www.synopsys.com/blogs/software-security/cyrc-advisory-open5gs/"}]},"description":{"description_data":[{"lang":"eng","value":"When Open5GS UPF receives a PFCP Session Establishment Request, it stores related values for building the PFCP Session Establishment Response.
