CWE-754

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.

Affected configurations

• linux linux kernel (< 4.17) • canonical ubuntu linux 12.04 • canonical ubuntu linux 14.04 • canonical ubuntu linux 16.04 • canonical ubuntu linux 18.04 • debian debian linux 8.0
