漏洞描述
中文描述:
libssh2是一款实现SSH2协议的客户端C库,它能够执行远程命令、文件传输,同时为远程的程序提供安全的传输通道。 libssh2中对键盘提示请求处理的方法存在输入验证错误漏洞,该漏洞源于userauth_keyboard_interactive()函数没有正确地检查服务器所发送提示的数量。远程攻击者可利用该漏洞在客户端系统上执行代码。
英文描述:
An integer overflow flaw, which could lead to an out of bounds write, was discovered in libssh2 before 1.8.1 in the way keyboard prompt requests are parsed. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.
