TITLE

SQLite Integer overflow vulnerability

DESCRIPTION

SQLite before 3.25.3, when the FTS3 extension is enabled, encounters an integer overflow (and resultant buffer overflow) for FTS3 queries in a "merge" operation that occurs after crafted changes to FTS3 shadow tables, allowing remote attackers to execute arbitrary code by leveraging the ability to run arbitrary SQL statements (such as in certain WebSQL use cases). This is a different vulnerability than CVE-2018-20346. SQLite Contains an integer overflow vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. SQLite is prone to a remote code-execution vulnerability. Attackers can exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will result in denial-of-service conditions. SQLite versions prior to 3.25.3 are vulnerable. SQLite is an open source embedded relational database management system based on C language developed by American D.Richard Hipp software developer. The system has the characteristics of independence, isolation and cross-platform. Currently there is no information about this vulnerability, please keep an eye on CNNVD or vendor announcements.
