CVE-2011-1550— Gentoo logrotate默认配置后置链接漏洞

一分钟漏洞结论

影响对象

n/a n/a

利用判断

尚无明确在野利用证据，仍需结合暴露面评估

建议动作

优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。

logrotate是一款系统日志管理软件。基于SUSE openSUSE Factory的logrotate的默认配置使用根权限去处理目录中的文件（允许低权限用户对该文件执行写操作）。本地用户可以利用logrotate支持不可信路径的缺陷，执行符号链接和硬链接攻击。该漏洞已经通过（1）cobbler，（2）inn，（3）safte-monitor和（4）uucp包的目录得到证实。

Vulnerability Description

The default configuration of logrotate on SUSE openSUSE Factory uses root privileges to process files in directories that permit non-root write access, which allows local users to conduct symlink and hard link attacks by leveraging logrotate's lack of support for untrusted directories, as demonstrated by directories for the (1) cobbler, (2) inn, (3) safte-monitor, and (4) uucp packages.
