Ubuntu Security Notice USN-3536-1
January 17, 2018

eglibc vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 ESM

Summary:

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

Software Description:
- eglibc: GNU C Library

Details:

It was discovered that the GNU C library did not properly handle all of
the possible return values from the kernel getcwd(2) syscall. A local
attacker could potentially exploit this to execute arbitrary code in setuid
programs and gain administrative privileges. (CVE-2018-1000001)

Update instructions:

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

Ubuntu 12.04 ESM:
libc6 2.15-0ubuntu10.21

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