CVE-2017-7184

Published: 19 March 2017

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.

From the Ubuntu security team

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.

Priority

CVSS 3 base score: 7.8
