{"id":"CVE-2022-39063","details":"When Open5GS UPF receives a PFCP Session Establishment Request, it stores related values for building the PFCP Session Establishment Response. 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.","modified":"2026-08-12T03:51:18.872670881Z","published":"2022-09-16T18:02:12Z","database_specific":{"cwe_ids":["CWE-676"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/39xxx/CVE-2022-39063.json","unresolved_ranges":[{"extracted_events":[{"fixed":"2.4.9"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"SNPS"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/39xxx/CVE-2022-39063.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39063"},{"type":"ADVISORY","url":"https://www.synopsys.com/blogs/software-security/cyrc-advisory-open5gs/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/open5gs/open5gs","events":[{"introduced":"0"},{"last_affected":"ff5023e95b01ed2b01339d854e19829aedea6eef"}],"database_specific":{"cpe":"cpe:2.3:a:open5gs:open5gs:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"2.4.9"}],"source":"CPE_RANGE"}}],"versions":["v2.4.9","v2.4.8","v2.4.7","v2.4.5","v2.4.4","v2.4.3","v2.4.1","v2.4.0","v2.3.6","v2.3.2","v2.3.0","v2.2.9","v2.2.8","v2.2.7","v2.2.6","v2.2.1","v2.2.0","v2.1.7","v2.1.5","v2.1.4","v2.1.3","v2.1.1","v2.1.0","v2.0.22","v2.0.18","v2.0.0","v1.3.0","v1.2.4","v1.2.3","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.0","v0.5.2","v0.5.1","v0.5.0","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.3.10","v0.3.8","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.0","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-39063.json"}}],"schema_version":"1.9.0"}
