# LinuxKit Security Events
|
|
|
|
The incomplete list below is an assessment of some CVEs, and LinuxKit's resilience
|
|
(or not) to them.
|
|
|
|
### Bugs mitigated:
|
|
|
|
* [CVE-2017-9075](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-9075):
|
|
Requires CONFIG_IP_SCTP=y, which we do not set.
|
|
* [CVE-2017-9076](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-9076):
|
|
Requires CONFIG_IP_DCCP=y, which we do not set. (However, we are vulnerable
|
|
to the ipv6 pieces that this patch fixes.)
|
|
* [CVE-2017-1000363](http://www.openwall.com/lists/oss-security/2017/05/23/16):
|
|
This CVE requires `CONFIG_PRINTER=y`, so we are not vulnerable.
|
|
* [CVE-2017-2636](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-2636)
|
|
([exploit post](https://a13xp0p0v.github.io/2017/03/24/CVE-2017-2636.html)):
|
|
This CVE requires `CONFIG_N_HDLC={y|m}`, which LinuxKit does not specify, and so
|
|
is not vulnerable.
|
|
* [CVE-2016-10229](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-10229)
|
|
This CVE only applies to kernels `<= 4.5, <= 4.4.21`. By using recent kernels
|
|
(specifically, kernels `=> 4.9, >= 4.4.21`, LinuxKit mitigates this bug.
|
|
|
|
### Bugs fixed:
|
|
|
|
* [CVE-2017-8890](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8890)
|
|
All users can do `accept()`, mitigated for kernels `>= 4.9.31, >= 4.10.16, >= 4.11.2` now packaged by LinuxKit
|
|
* [CVE-2017-9077](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-9077)
|
|
Same as CVE-2017-8890, but for ipv6.
|
|
* [CVE-2017-9074](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-9074):
|
|
Users have access to ipv6 sockets, mitigated for kernels `>= 4.9.31, >= 4.10.16, >= 4.11.2` now packaged by LinuxKit
|
|
* [CVE-2017-9242](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-9242):
|
|
Same as CVE-2017-9074.
|
|
* [CVE-2017-9076](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-9076):
|
|
Users have access to ipv6 sockets (note that part of this is mitigated as
|
|
well, so listed above: we do not set CONFIG_IP_DCCP), mitigated for kernels
|
|
`>= 4.9.31, >= 4.10.16, >= 4.11.2` now packaged by LinuxKit
|
|
|
