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)
