GHOST, a critical Linux security hole, is revealed
Researchers at cloud security company Qualys have discovered a major security hole, GHOST (CVE-2015-0235), in the Linux GNU C Library (glbibc). This vulnerability enables hackers to remotely take control of systems without even knowing any system IDs or passwords.
Qualys alerted the major Linux distributors about the security hole quickly and most have now released patches for it. Josh Bressers, manager of the Red Hat product security team said in an interview that, "Red Hat got word of this about a week ago. Updates to fix GHOST on Red Hat Enterprise Linux (RHEL) 5, 6, and 7 are now available via the Red Hat Network."
This hole exists in any Linux system that was built with glibc-2.2, which was released on November 10, 2000. Qualys found that the bug had actually been patched with a minor bug fix released on May 21, 2013 between the releases of glibc-2.17 and glibc-2.18.
