Description GLSAMaker/CVETool Bot gentoo-dev 2017-11-03 14:52:44 UTC 
CVE-2016-10124 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2016-10124):
  An issue was discovered in Linux Containers (LXC) before 2016-02-22. When
  executing a program via lxc-attach, the nonpriv session can escape to the
  parent session by using the TIOCSTI ioctl to push characters into the
  terminal's input buffer, allowing an attacker to escape the container.
Comment 1 Christopher Díaz Riveros (RETIRED) gentoo-dev Security 2017-11-03 14:54:05 UTC 
@Maintainers LXC 1.0.8 seems to be vulnerable, please stabilize a more recent version.

Thank you.
Comment 2 Agostino Sarubbo gentoo-dev 2017-11-05 11:46:49 UTC 
the current stable 2.0.7 contains the fix.

However if the attacker can escape the container, I guess has a major rate than 4, I'm setting it to 2.
