• Status: RESOLVED FIXED

CAN-2004-0972

The lvmcreate_initrd script in the lvm package in Trustix Secure Linux
1.5 through 2.1, and possibly other operating systems, allows local
users to overwrite files via a symlink attack on temporary files.

We have two lvm packages in our tree, lvm-user for LVM 1.* and lvm2 for LVM 2.*. The script is only in LVM 1.* releases. So we should either remove the package or fix it :)

[Comment 3 Thierry Carrez (RETIRED) 2004-10-30 09:27:54 UTC]

base-system: please either fix this or remove lvm-user altogether. I'm sure you prefer we don't mess with it ourselves :)
