Description Sam Fowler 2018-04-20 01:02:39 EDT

LibreOffice before versions 5.4.5.1 and 6.0.1.1 is vulnerable to an integer overflow resulting in a write to recently freed data in the StgSmallStrm class from sot/source/sdstor/stgstrms.cxx. An attacker could exploit this to cause a denial of service or other unspecified impact via a crafted document.
