Ubuntu 16.04LTS/18.04 LTS: Linuxカーネル脆弱性 (USN-5164-1)

medium Nessus プラグイン ID 155747

言語:

概要

リモート Ubuntu ホストに 1 つ以上のセキュリティ更新がありません。

説明

リモートのUbuntu16.04LTS/18.04 LTSホストには、USN-5164-1のアドバイザリに記載された複数の脆弱性の影響を受けるパッケージがインストールされています。

 - 5.13.4までのLinuxカーネルのdrivers/net/usb/hso.cのhso_free_net_deviceは、NETREG_REGISTERED状態をチェックせずにunregister_netdevを呼び出し、メモリ解放後使用 (Use After Free) と二重解放を引き起こします。
 (CVE-2021-37159)

 - Linux カーネルの drivers/crypto/ccp/ccp-ops.c の ccp_run_aes_gcm_cmd() 関数にメモリリークの欠陥が見つかりました。攻撃者がサービス拒否 (メモリ消費) を引き起こす可能性があります。
 この脆弱性は以前の CVE-2019-18808 に類似しています。(CVE-2021-3744)

Nessus はこの問題をテストしておらず、代わりにアプリケーションの自己報告されたバージョン番号にのみ依存しています。

ソリューション

影響を受けるパッケージを更新してください。
