CVE-2018-18690

Priority
Description
In the Linux kernel before 4.17, a local attacker able to set attributes on
an xfs filesystem could make this filesystem non-operational until the next
mount by triggering an unchecked error condition during an xfs attribute
change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c
mishandles ATTR_REPLACE operations with conversion of an attr from short to
long form.
Ubuntu-Description
Kanda Motohiro discovered that writing extended attributes to an XFS file
system in the Linux kernel in certain situations could cause an error
condition to occur. A local attacker could use this to cause a denial of
service.
