USN-3323-1: GNU C Library vulnerability

19 June 2017

Gnu C library could be made to run programs as an administrator.




It was discovered that the GNU C library did not properly handle memory
when processing environment variables for setuid programs. A local attacker
could use this in combination with another vulnerability to gain
administrative privileges.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 17.04
Ubuntu 16.10
Ubuntu 16.04
Ubuntu 14.04

After a standard system update you need to reboot your computer to make
all the necessary changes.
