Details

Fernando Muñoz discovered that HTML Tidy incorrectly handled memory. If a
user or automated system were tricked into processing specially crafted
data, applications linked against HTML Tidy could be made to crash, leading
to a denial of service, or possibly execute arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 15.04
Ubuntu 14.04
Ubuntu 12.04

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