漏洞描述

Logwatch是一款专门Linux log文件（日志文件）的软件。命令行中的特殊字符从logwatch传递给sh时缺少正确过滤，当Samba用户使用恶意的3836jai)xoh)名登录时会在系统上创建名为log.3836jai)xoh)的日志文件。logwatch:sh: -c: line 0: syntax error near unexpected token `)'sh: -c: line 0: `cat /var/log/samba/log. 4023 /var/log/sa ................很明显这可允许以root特权远程执行命令，如以"; rm -rf /"登录。
