Incomplete Requirements for setattr Operations in Linux Kernel 3.x Allows Capability Stripping Denial of Service Vulnerability

CVE-2015-1350 · MEDIUM Severity

CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allows local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program.
