CVE-2015-4551
タイトル: CVE-2015-4551 Arbitrary file disclosure in Calc and Writer
アナウンス: November 5, 2015
Fixed in: LibreOffice 4.4.5/5.0.0
詳細:
The LinkUpdateMode feature controls whether documents inserted into Writer or Calc via links will either not get updated, or prompt to update, or automatically update, when the parent document is loaded. The configuration of this option was stored in the document. That flawed approach enabled documents to be crafted with links to plausible targets on the victims host computer. The contents of those automatically inserted after load links can be concealed in hidden sections and retrieved by the attacker if the document is saved and returned to sender, or via http requests if the user has selected lower security settings for that document.
All users are recommended to upgrade to LibreOffice >= 4.4.5 or >= 5.0.0
Thanks to Federico "fox" Scrinzi for discovering this flaw.
