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.
