x86_64 プラットフォーム上で稼動する Linux kernel の IA32 システムコールエミュレーション機能における権限昇格の脆弱性

Title	x86_64 プラットフォーム上で稼動する Linux kernel の IA32 システムコールエミュレーション機能における権限昇格の脆弱性
Summary	x86_64 プラットフォーム上で稼動する Linux kernel の arch/x86/ia32/ia32entry.S 内にある IA32 システムコールエミュレーション機能は、32 ビット互換の ptrace システムコールを処理後に eax レジスタをゼロ拡張させないため、権限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、rax レジスタを使用時にシステムコールテーブルの領域外へのアクセスを誘発され、権限を取得される可能性があります。
Solution	ベンダ情報及び参考情報を参照して適切な対策を実施してください。

NVD Vulnerability Information

CVE-2010-3301

Summary	The IA32 system call emulation functionality in arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.36-rc4-git2 on the x86_64 platform does not zero extend the %eax register after the 32-bit entry path to ptrace is used, which allows local users to gain privileges by triggering an out-of-bounds access to the system call table using the %rax register. NOTE: this vulnerability exists because of a CVE-2007-4573 regression.
