Description
This security bulletin contains information about 1 security vulnerability.
1) Resource management errors (CVE-ID: CVE-2015-3332)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
A certain backport in the TCP Fast Open implementation for the Linux kernel before 3.18 does not properly maintain a count value, which allow local users to cause a denial of service (system crash) via the Fast Open feature, as demonstrated by visiting the chrome://flags/#enable-tcp-fast-open URL when using certain 3.10.x through 3.16.x kernel builds, including longterm-maintenance releases and ckt (aka Canonical Kernel Team) builds.
