NetBSD PPP驱动远程溢出漏洞

NetBSD是一款免费开放源代码的UNIX性质的操作系统。 在处理从远程主机所接收到的连接控制协议LCP配置选项时，ppp4没有正确的验证选项长度，这可能导致在所分配的内核内存缓冲区以外读取或写入数据。 能够发送LCP报文的攻击者，包括ppp4连接的远端，可以导致内核忙碌、获得敏感信息或权限提升。 FreeBSD FreeBSD 6.x FreeBSD FreeBSD 5.5 FreeBSD FreeBSD 5.4 FreeBSD FreeBSD 5.3 FreeBSD FreeBSD 4.x NetBSD NetBSD 4.0Beta NetBSD NetBSD 3.1RC1 NetB...

CVE-2006-4304

Buffer overflow in the sppp driver in FreeBSD 4.11 through 6.1, NetBSD 2.0 through 4.0 beta before 20060823, and OpenBSD 3.8 and 3.9 before 20060902 allows remote attackers to cause a denial of service panic, obtain sensitive information, and possibly execute arbitrary code via crafted Link Contr...

CVE-2006-4304

CVE-2006-4304 describes a buffer overflow in the sppp(4) driver (used with PPP implementations such as pppoe/ippp) on FreeBSD 4.11–6.1, NetBSD 2.0–4.0 beta, and OpenBSD 3.8–3.9. The issue arises while processing LCP configuration options, where option lengths aren’t properly validated, allowing a...

sppp -- buffer overflow vulnerability

Problem Description While processing Link Control Protocol LCP configuration options received from the remote host, sppp4 fails to correctly validate option lengths. This may result in data being read or written beyond the allocated kernel memory buffer. Impact An attacker able to send LCP packet...
