medium Nessus Plugin ID 247597
語言:
概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，供應商表示將不會修補。說明
Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。- usbnetgl620a修正genelink_bind() 中的端點檢查。Syzbot 報告 [1] 在 usb_submit_urb() 中的警告是由 gl620a 驅動程式中預期和實際存在的端點之間的不一致所觸發。由於genelink_bind() 未正確驗證指定的 eps 實際上是否由裝置提供在此情況下為一種人為製造的 eps 可能會出現不相符情況。藉由使用 usbnet 公用程式函式 usbnet_get_endpoints() (通常是專門為此問題保留) 來修正此問題。檢查端點若有遺漏請提早傳回。 [1] Syzbot reportusb 5-1製造商syz usb 5-1SerialNumbersyz usb 5-1config 0 描述符號?? gl620a 5-1:0.23 usb0在 usb-dummy_hcd.0-1, ... 登錄 'gl620a' ------------[cut here ]----------- - usb 5-1BOGUS urb xfer、pipe 3 != type 1 警告
