USN-3536-1: GNU C Library vulnerability

Releases

• Ubuntu 12.04

Packages

• 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

• libc6 - 2.15-0ubuntu10.21

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