Linux Kernel \'/proc/net/udp本地拒绝服务漏洞

BUGTRAQ ID: 34329 CNCAN ID：CNCAN-2009040205 Linux是一款开放源代码的操作系统。 Linux内核中的udp seq_file基础架构使用错误的锁代码，本地攻击者可以利用漏洞对系统进行拒绝服务攻击。 从/proc/net/udp或者从其他使用相同seq_file udp基础架构的文件中读取零字节，可导致触发kernel Panic，造成拒绝服务攻击。 Linux kernel 2.6.29 -git1 Linux kernel 2.6.29 Linux kernel 2.6.28 9 Linux kernel 2.6.28 8 Linux kernel 2.6.28 6 Linux kernel 2.6.28 5 Linux kernel 2.6.28 3 Linux kernel 2.6.28 2 Linux kernel 2.6.28 1 Linux kernel 2.6.28 -rc7 Linux kernel 2.6.28 -rc5 Linux kernel 2.6.28 -git7 Linux kernel 2.6.28 Linux kernel 2.6.29-rc2-git1 Linux kernel 2.6.29-rc2 Linux kernel 2.6.29-rc1 Linux kernel 2.6.28.4 可升级内核程序： Linux kernel 2.6.29-rc2 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.29-rc2-git1 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.28.4 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.29-rc1 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.28 2 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.28 5 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.28 6 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.28 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.28 3 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.28 8 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.28 1 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.28 9 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.28 -rc7 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.28 -rc5 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.28 -git7 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.29 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2 Linux kernel 2.6.29 -git1 Linux patch-2.6.29-git8.bz2 <a href=http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz target=_blank rel=external nofollow>http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.29-git8.bz</a> 2
