CVE-2018-13100

Priority
Description
An issue was discovered in fs/f2fs/super.c in the Linux kernel through
4.17.3, which does not properly validate secs_per_zone in a corrupted f2fs
image, as demonstrated by a divide-by-zero error.
Ubuntu-Description
Wen Xu discovered that the f2fs file system implementation in the Linux
kernel did not properly validate metadata. An attacker could use this to
construct a malicious f2fs image that, when mounted, could cause a denial
of service (system crash).

 sbeattie> fix subject 'f2fs: fix to do sanity check with secs_per_zone'
 tyhicks> The affected user base for this issue is likely small since f2fs is
  not the default filesystem and it is not widely used in Ubuntu
