Bug#427402: kernel-panic with removable media devices possible



Package: pmount
Version: 0.9.13-2
Severity: important
Tags: security

--- Please enter the report below this line. ---

One could crash (kernel-panic) someones system by only providing an erroneous 
ext2/3 with error-behavior in the superblock set to panic on a removable 
media device e.g. a memory stick. (This ist done with tune2fs -e panic ...)
When the filesystem is being mounted the system kernel-panics.
On systems which automatically mount plugged in devices this is fatal.

So pmount should imply the option errors=continue to mount on filesystems 
supporting it.
