Ubuntu 14.04 LTS : HTML Tidy vulnerabilities (USN-2695-1)

high Nessus Plugin ID 85123

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2695-1 advisory.

 Fernando Muoz 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected libtidy-0.99-0, libtidy-dev and / or tidy packages.
