Description
sot/source/sdstor/stgstrms.cxx in LibreOffice before 5.4.5.1 and 6.x before 6.0.1.1 uses an incorrect integer data type in the StgSmallStrm class, which allows remote attackers to cause a denial of service (use-after-free with write access) or possibly have unspecified other impact via a crafted document that uses the structured storage ole2 wrapper file format.
