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. Apple Has released an update for each product.The expected impact depends on each vulnerability, but can be affected as follows: * Sandbox avoidance * Arbitrary code execution * Privilege escalation * information leak * Information falsification * Service operation interruption (DoS) * Arbitrary script execution. 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. A security vulnerability exists in SQLite versions prior to 3.25.3. Currently there is no information about this vulnerability, please keep an eye on CNNVD or vendor announcements. Alternatively, on your watch, select "My Watch > General > About". ========================================================================= Ubuntu Security Notice USN-4019-1 June 19, 2019 sqlite3 vulnerabilities ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 19.04 - Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS Summary: Several security issues were fixed in SQLite.
