    Apache HTTP Server の 5 件の脆弱性が FIX：広大な攻撃範囲を持つ RCE など https://iototsecnews.jp/2026/05/05/critical-apache-http-server-flaw-exposes-millions-of-servers-to-rce-attacks/ 今回の脆弱性の主な原因は、メモリ管理の不備や設定の不備にあります。最も深刻な CVE-2026-23918 は、一度解放されたメモリをプログラムが誤って解放してしまう double-free という現象が HTTP/2 の処理中に発生します。これによりメモリの状態が壊れ、攻撃者に操作される恐れがあります。また CVE-2026-24072 では設定ファイルの評価処理の不備から、本来見えないはずのファイルが読み取られてしまいます。他にも CVE-2026-28780 のような容量制限を超えてデータが書き込まれるバッファ・オーバーフローや、CVE-2026-29168 のリソース割り当て制限の不足、CVE-2026-29169 の NULL ポインタ参照など、プログラムが想定外の挙動をする隙が原因となっています。ご利用のチームは、ご注意ください。 #Apache #CVE202623918 #CVE202624072 #CVE202628780 #CVE202629168 #CVE202629169 #HTTPServer #Vulnerability
