漏洞描述
中文描述:
PuTTY是软件开发者Simon Tatham所研发的一套免费的Telnet、Rlogin和SSH客户端软件。该软件主要用于对Linux系统进行远程管理。 PuTTY 0.55之前版本在处理畸形包数据时存在问题,远程攻击者可以利用这个漏洞构建恶意服务器,诱使putty访问,可以用户进程权限在系统上执行任意指令。Core Security小组发现putty存在一个严重问题。允许SSH2服务器在主机KEY验证之前攻击putty客户端。攻击者可以构建恶意SSH服务器,让putty用户连接时触发此漏洞。
英文描述:
Multiple heap-based buffer overflows in the modpow function in PuTTY before 0.55 allow (1) remote attackers to execute arbitrary code via an SSH2 packet with a base argument that is larger than the mod argument, which causes the modpow function to write memory before the beginning of its buffer, and (2) remote malicious servers to cause a denial of service (client crash) and possibly execute arbitrary code via a large bignum during authentication.
