Updated libcdio packages fix security vulnerabilities

A heap corruption bug was found in the way libcdio handled processing of ISO files. An attacker could potentially use this flaw to crash applications using libcdio by tricking them into processing crafted ISO files, thus resulting in local DoS (CVE-2017-18198).

A NULL pointer dereference flaw was found in the way libcdio handled processing of ISO files. An attacker could potentially use this flaw to crash applications using libcdio by tricking them into processing crafted ISO files (CVE-2017-18199).

A double-free flaw was found in the way libcdio handled processing of ISO files. An attacker could potentially use this flaw to crash applications using libcdio by tricking them into processing crafted ISO files (CVE-2017-18201).

libcdio vulnerabilities

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)
