=================================== Overview ===================================
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.
================================= Our Analysis =================================
----- Affected Products -----
LibreOffice 5.3.7.2 as originally packaged in Cucumber Linux 1.0 and 1.1 is
vulnerable.
----- Scope and Impact of this Vulnerability -----
Denial of service (use after free) resulting in other possible unspecified
impacts via a specially crafter document.
----- Fix for this Vulnerability -----
Fixed in commit: https://gerrit.libreoffice.org/gitweb?p=core.git;a=patch;h=fdd41c995d1f719e92c6f083e780226114762f05
