libcdio vulnerabilities
==========================================================================

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

- Ubuntu 16.04 ESM
- Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in libcdio.

Software Description:
- libcdio: library to read and control digital audio CDs (development files)

Details:

Zhao Liang discovered that libcdio was not properly performing memory
management operations when processing ISO files, which could result
in a heap buffer overflow or in a NULL pointer dereference. If a user
or automated system were tricked into opening a specially crafted file,
an attacker could possibly use this issue to cause a denial of service.
(CVE-2017-18198, CVE-2017-18199)

Update instructions:

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