在/etc/group文件丢失时,Slackware Linux 3.2至3.5版本的登录不能正确的检测错误,该漏洞将导致该文件特权下降,导致它的根特权分配给任意登录到服务器上的本地用户。

漏洞公告

Upgrade to a later version of Slackware. This problem was fixed in version subsequent to 3.5.
If source is available, checking the return value from the set_uid_gid call and exiting if it is not 0 will prevent this from being a problem, although this may be overly restrictive.
