[slackware-security] util-linux umount privilege escalation (SSA:2005-255-02)
New util-linux packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, and -current to fix a security issue with umount. A bug in the '-r' option could allow flags in /etc/fstab to be improperly dropped on user-mountable volumes, allowing a user to gain root privileges.
For more details, see David Watson's post to BugTraq:
http://www.securityfocus.com/archive/1/410333
Here are the details from the Slackware 10.1 ChangeLog: +--------------------------+ patches/packages/util-linux-2.12p-i486-2.tgz: Patched an issue with umount where if the umount failed when the '-r' option was used, the filesystem would be remounted read-only but without any extra flags specified in /etc/fstab. This could allow an ordinary user able to mount a floppy or CD (but with nosuid, noexec, nodev, etc in /etc/fstab) to run a setuid binary from removable media and gain root privileges. Reported to BugTraq by David Watson: http://www.securityfocus.com/archive/1/410333 (* Security fix *) +--------------------------+
