Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

It was discovered that LibreOffice incorrectly handled certain document files. If a user were tricked into opening a specially crafted document, a remote attacker could cause LibreOffice to crash, and possibly execute arbitrary code. (CVE-2018-10119, CVE-2018-10120, CVE-2018-11790)

It was discovered that LibreOffice incorrectly handled embedded SMB connections in document files. If a user were tricked in to opening a specially crafted document, a remote attacker could possibly exploit this to obtain sensitive information. (CVE-2018-10583)

Alex Infuhr discovered that LibreOffice incorrectly handled embedded scripts in document files. If a user were tricked into opening a specially crafted document, a remote attacker could possibly execute arbitrary code. (CVE-2018-16858).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libreoffice-core package.
