[USN-141-1] tcpdump vulnerability-优快云博客

2005年6月21日发布的Ubuntu安全公告USN - 141 - 1指出，Ubuntu 4.10和5.04版本的tcpdump存在安全漏洞，特定无效BGP数据包会使tcpdump陷入无限循环，攻击者可借此绕过网络流量分析。可通过升级tcpdump包来修复，文中还给出了各架构更新包的下载链接。

Ubuntu Security Notice USN-141-1 June 21, 2005

tcpdump vulnerability

CAN-2005-1267

===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

Ubuntu 5.04 (Hoary Hedgehog)

The following packages are affected:

tcpdump

The problem can be corrected by upgrading the affected package to

version 3.8.3-3ubuntu0.3 (for Ubuntu 4.10), or 3.8.3-3ubuntu0.4 (for

Ubuntu 5.04). In general, a standard system upgrade is sufficient to

effect the necessary changes.

Details follow:

It was discovered that certain invalid BGP packets triggered an

infinite loop in tcpdump, which caused tcpdump to stop working. This

could be abused by a remote attacker to bypass tcpdump analysis of

network traffic.
