Description

Federico Scrinzi discovered that LibreOffice incorrectly handled documents inserted into Writer or Calc via links. If a user were tricked into opening a specially crafted document, a remote attacker could possibly obtain the contents of arbitrary files. (CVE-2015-4551)

It was discovered that LibreOffice incorrectly handled PrinterSetup data stored in ODF files. If a user were tricked into opening a specially crafted ODF document, a remote attacker could cause LibreOffice to crash, and possibly execute arbitrary code. (CVE-2015-5212)

It was discovered that LibreOffice incorrectly handled the number of pieces in DOC files. If a user were tricked into opening a specially crafted DOC document, a remote attacker could cause LibreOffice to crash, and possibly execute arbitrary code. (CVE-2015-5213)

It was discovered that LibreOffice incorrectly handled bookmarks in DOC files. If a user were tricked into opening a specially crafted DOC document, a remote attacker could cause LibreOffice to crash, and possibly execute arbitrary code. (CVE-2015-5214).

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.
