kernel: rt_cache leak leads to lack of network connectivity

The icmpsend function in net/ipv4/icmp.c in the Linux kernel before 2.6.25, when configured as a router with a REJECT route, does not properly manage the Protocol Independent Destination Cache aka DST in some situations involving transmission of an ICMP Host Unreachable message, which allows remo...

Linux Kernel /proc/net/rt_cache远程拒绝服务漏洞

BUGTRAQ ID: 34084 CVECAN ID: CVE-2009-0778 Linux Kernel是开放源码操作系统Linux所使用的内核。 即使缓存的路由表保持不变，/proc/slabinfo中的ipdstcache值也会一直递增，这会导致ipdstcache最终会到达 /proc/sys/net/ipv4/route/maxsize的值。当到达该值的时候，内核就会报告“dst cache overflow”，之后服务器不再响应任何网络活动。 Linux kernel 2.6.x 临时解决方法： 删除REJECT路由，或用ip route add 10.10.0.0/16...

CVE-2009-0778

CVE-2009-0778 affects the Linux kernel prior to 2.6.25 when configured as a router with a REJECT route. The icmp_send code in net/ipv4/icmp.c can mishandle the Protocol Independent Destination (DST) cache, potentially leaking DST state and allowing remote attackers to cause a denial of service (c...

Windows Vista iphlpapi.dll本地内核栈溢出漏洞

BUGTRAQ ID: 32357 Windows Vista是微软发布的最新版本的操作系统。 在使用CreateIpForwardEntry2方式向IPv4路由表添加路由项时，如果对MIBIPFORWARDROW2结构所包含的DestinationPrefix结构中的目标PrefixLength成员传送了大于32的非法值的话，就会破坏内核空间内存，导致随机的蓝屏崩溃。传送的非法值越大，所触发的崩溃就会越快出现。 此外如果使用系统自带的route add命令并在子网掩码中使用了非法值的话，该命令也可以触发相同的缓冲区溢出。 Microsoft Windows Vista Microsof...
