DESCRIPTION

* CVE-2019-11477, CVE-2019-11478, CVE-2019-11479: Remote Denial-of-service in
TCP stack.

A number of errors in the TCP stack could result in a remotely
triggerable denial of service on links with a small Maximum Segment Size
(MSS). A remote user could use a maliciously crafted TCP stream to
either panic the system or exhaust resources.

A new sysctl, ksplice_net_ipv4.tcp_min_snd_mss can be used to to adjust
the minimum Maximum Segment Size and defaults to 48 bytes.

SUPPORT

Ksplice support is available at ksplice-support_ww@oracle.com.
