Release Date

22nd July 2020.


The vcore database container was found to contain some vulnerable software. Almost all of the vulnerabilities were found to have no impact on our product. However there was one vulnerability that presented a small opportunity for an internal actor to cause a denial of service (DoS).

  • Vaion vcore: All Stable Upgrade Channel versions before 2.3.4

Unaffected Products

  • Vaion vcam: All versions.

This issue has been fixed in vcore Beta Upgrade Channel version 2.3.1 and Stable Upgrade Channel version 2.3.4. We recommended that all vcore installations running an affected version upgrade to the latest release at their earliest convenience. Releases are available to download through the vcore user interface.

Vulnerability Information

vcore uses a database container exposed internally on the server. The database software makes use of a library used for unicode text handling which was vulnerable to an integer overflow vulnerability. It is possible for an authenticated user using the vcore user interface to store unicode text into the database which, when handled by the vulnerable code, could cause a crash of the db container.
