- 漏洞讨论

Due to insecure /tmp file creation the sadc command under some versions of AIX is vulnerable to a symlink attack. This results in normal users being able to create and/or modify files owned by group 'adm'. The /usr/lib/sa/sadc command does drop the effective group id before opening or creating the filename passed in on the command line.
