SCOOpenServer5.0至5.0.6版本包含的lpusers存在漏洞。本地用户可以借助’-u’命令行参数的缓冲区溢出攻击提升额外特权。

SCO OpenServer 5.0.6 (and possibly earlier versions) ships with several suid bin executables used in printer administration and related tasks.

This includes lpusers, a component used to set the queue priority of jobs submitted to the LP print service by users.
'lpusers' contains a locally exploitable buffer overflow vulnerability that occurs when commandline arguments are of excessive length.

If properly exploited, this can yield root privilege to the attacker.

/opt/K/SCO/Unix/5.0.6Ga/usr/lib/lpusers -u `perl -e 'print "A" x 700'`

Memory fault - core dumped
