Prior to version 6.1.12, the USB DFU UPLOAD functionality may be utilized to introduce a buffer overflow resulting in overwrite of memory contents. In particular cases this may allow an attacker to bypass security features or execute arbitrary code. The implementation of `ux_device_class_dfu_control_request` function prevents buffer overflow during handling of DFU UPLOAD command when current state is `UX_SYSTEM_DFU_STATE_DFU_IDLE`. This issue has been patched, please upgrade to version 6.1.12. As a workaround, add the `UPLOAD_LENGTH` check in all possible states.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2022-11-04 20:15:00","updated_at":"2022-11-07 17:22:00"},"problem_types":["CWE-120"],"metrics":[],"references":[{"url":"https://github.com/azure-rtos/usbx/security/advisories/GHSA-m9p8-xrp7-vvqp","name":"https://github.com/azure-rtos/usbx/security/advisories/GHSA-m9p8-xrp7-vvqp","refsource":"CONFIRM","tags":[],"title":"DFU UPLOAD buffer overflow revised · Advisory · azure-rtos/usbx · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-39344","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39344","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"39344","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"microsoft","cpe5":"azure_rtos_usbx","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"security-advisories@github.com","ID":"CVE-2022-39344","STATE":"PUBLIC","TITLE":"Azure RTOS USBX vulnerable to buffer overflow "},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"usbx","version":{"version_data":[{"version_value":"< 6.1.12"}]}}]},"vendor_name":"azure-rtos"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"Azure RTOS USBX is a USB host, device, and on-the-go (OTG) embedded stack, that is fully integrated with Azure RTOS ThreadX.
