Linux kernel の do_tcp_setsockopt 関数におけるサービス運用妨害 (DoS) の脆弱性

Title	Linux kernel の do_tcp_setsockopt 関数におけるサービス運用妨害 (DoS) の脆弱性
Summary	Linux kernel の net/ipv4/tcp.c 内にある do_tcp_setsockopt 関数は、TCP_MAXSEG の値を適切に制限しないため、サービス運用妨害 (DoS) 状態となる脆弱性が存在します。
Possible impacts	ローカルユーザにより、setsockopt コールを介して、ゼロ除算エラーまたは符号付き整数の不適切な使用を誘発され、サービス運用妨害 (DoS) 状態にされる可能性があります。 ※specifies a small value は翻訳しておりません

NVD Vulnerability Information

CVE-2010-4165

Summary	The do_tcp_setsockopt function in net/ipv4/tcp.c in the Linux kernel before 2.6.37-rc2 does not properly restrict TCP_MAXSEG (aka MSS) values, which allows local users to cause a denial of service (OOPS) via a setsockopt call that specifies a small value, leading to a divide-by-zero error or incorrect use of a signed integer.
