Description Agostino Sarubbo gentoo-dev 2016-06-30 09:02:29 UTC
From ${URL} :

A use after free vulnerability was found in RTF parser of LibreOffice. The vulnerability lies in the parsing of documents containing both stylesheet and 
superscript tokens. A specially crafted RTF document containing both a stylesheet and superscript element causes LibreOffice to access an invalid pointer 
referencing previously used memory on the heap. By carefully manipulating the contents of the heap, this vulnerability can be used to execute arbitrary 
code.
