Subject: CVE-2018-14722: btrfsmaintenance: Code execution
Hi,
SUSE employee Fabian Vogt has found a shell code injection issue in the "btrfsmaintenance" tools.
https://bugzilla.suse.com/show_bug.cgi?id=1102721
Mounting btrfs images with a label including shell injection characters could cause
the cron jobs (running as root) to execute the include shellcode.
Our proposed fix attached to this email.
bad image can be created with:
mkfs.btrfs --label "`/evil/command`' /dev/sdx
Ciao, Marcus
