CVE-2017-7184

Priority
Description
The xfrm_replay_verify_len function in net/xfrm/xfrm_user.c in the Linux
kernel through 4.10.6 does not validate certain size data after an
XFRM_MSG_NEWAE update, which allows local users to obtain root privileges
or cause a denial of service (heap-based out-of-bounds access) by
leveraging the CAP_NET_ADMIN capability, as demonstrated during a Pwn2Own
competition at CanSecWest 2017 for the Ubuntu 16.10 linux-image-* package
4.8.0.41.52.
Ubuntu-Description
It was discovered that the xfrm framework for transforming packets in the
Linux kernel did not properly validate data received from user space. A
local attacker could use this to cause a denial of service (system crash)
or execute arbitrary code with administrative privileges.
Notes

  not supported on the Ubuntu Touch 14.10 and earlier preview kernels
 jdstrand> linux-lts-saucy no longer receives official support
