CVE-2019-9853

LibreOffice documents can contain macros. The execution of those macros is
controlled by the document security settings, typically execution of macros
are blocked by default. A URL decoding flaw existed in how the urls to the
macros within the document were processed and categorized, resulting in the
possibility to construct a document where macro execution bypassed the
security settings. The documents were correctly detected as containing
macros, and prompted the user to their existence within the documents, but
macros within the document were subsequently not controlled by the security
settings allowing arbitrary macro execution This issue affects: LibreOffice
6.2 series versions prior to 6.2.7; LibreOffice 6.3 series versions prior
to 6.3.1.
