USN-5558-1: libcdio vulnerabilities

10 August 2022

Several security issues were fixed in libcdio.



  • libcdio - library to read and control digital audio CDs (development files)


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 package versions:

Ubuntu 16.04
Ubuntu 14.04

In general, a standard system update will make all the necessary changes.
