Linux Kernel の fs/isofs/rock.c におけるカーネルメモリから重要な情報を取得される脆弱性

Title	Linux Kernel の fs/isofs/rock.c におけるカーネルメモリから重要な情報を取得される脆弱性
Summary	Linux Kernel の fs/isofs/rock.c 内の parse_rock_ridge_inode_internal 関数は、Extensions Reference (ER) System Use Field 内の length 値を検証しないため、カーネルメモリから重要な情報を取得される脆弱性が存在します。
Possible impacts	ローカルユーザにより、巧妙に細工された ISO9660 イメージを介して、カーネルメモリから重要な情報を取得される可能性があります。
Solution	ベンダより正式な対策が公開されています。ベンダ情報を参照して適切な対策を実施してください。
