wireshark: crash in the packet reassembling

The fragmentaddwork function in epan/reassemble.c in Wireshark 0.8.19 through 1.0.1 allows remote attackers to cause a denial of service crash via a series of fragmented packets with non-sequential fragmentation offset values, which lead to a buffer over-read...

Microsoft Windows PGM Fragment Handling Denial of Service (MS08-036; CVE-2008-1441)

PGM is a reliable and scalable multicast protocol that enables receivers to detect loss, request retransmission of lost data, or notify an application of unrecoverable loss. The vulnerability is due to the PGM's parsing code that fails to properly handle malformed PGM packets that contain an...

CVE-2008-1441: Improper Input Validation

Microsoft Windows XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, and Server 2008 allows remote attackers to cause a denial of service system hang via a series of Pragmatic General Multicast PGM packets with invalid fragment options, aka the "PGM Malformed Fragment Vulnerability."...

Microsoft Windows PGM Invalid Fragment Remote Denial Of Service Vulnerability

Description Microsoft Windows is prone to a remote denial-of-service vulnerability because it fails to adequately handle specially crafted PGM Pragmatic General Multicast network traffic. Attackers can exploit this issue to cause affected computers to stop responding until all the malformed packe...

Snort碎片重组TTL值导致漏报漏洞

BUGTRAQ ID: 29327 CVECAN ID: CVE-2008-1804 Snort是广泛部署的开放源码网络入侵检测系统（IDS）。 Snort没有正确地重组IP报文，远程攻击者可能利用此漏洞绕过检测。 在接收入站碎片时，Snort检查碎片的存活时间（TTL）值并与初始碎片的TTL做比较。如果二者之间的差异大于所配置的量（默认最大值为5）的话，就会丢弃碎片，也无法对其应用规则，这导致Snort无法过滤或检查有效的通讯。 Snort Project Snort 2.8 Snort Project Snort 2.6 临时解决方法：...

CVE-2008-1804

Linux Kernel Netfilter nf_conntrack IPv6报文重组绕过规则漏洞

Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel中netfilter的模块实现上存在漏洞，远程攻击者可能利用此漏洞绕过访问过滤。 netfilter的nfconntrack函数在重组碎片IPv6报文期间没有设置nfctinfo，将默认值初始化为0，而这是IPCTESTABLISHED的值，因此所有IPv6碎片都追踪为ESTABLISHED，这样攻击者就可以绕过某些接受ESTABLISHED报文的规则组。 Linux kernel 2.6.20.3 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载：...

Snort Inline模式碎片重组拒绝服务漏洞

Snort是广泛部署的开放源码网络入侵检测系统（IDS）。很多其他IDS产品中也使用了Snort及其组件。 Snort Inline在处理畸形的碎片报文时存在漏洞，远程攻击者可能利用此漏洞导致Snort崩溃。 如果在Linux平台上以Inline模式运行Snort的话，且启用了Frag3同时禁用了ipconntrack，则如果向Snort发送了特制的碎片报文的话就会导致拒绝服务。 Snort Project Snort 2.7.0 beta 1 Snort Project Snort 2.6.1.2 Snort Project Snort 2.6.1.1...
