What is CVE-2018-10120?

The SwCTBWrapper::Read function in LibreOffice, prior to specific versions, is vulnerable due to inadequate validation of a customizations index. This vulnerability potentially allows remote attackers to induce a denial of service condition characterized by a heap-based buffer overflow.
