Ubuntu Security Notice USN-4438-1
July 27, 2020

sqlite3 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS


SQLite could be made to crash or run programs if it processed a specially
crafted query.

Software Description:
- sqlite3: C library that implements an SQL database engine


It was discovered that SQLite incorrectly handled query-flattener
optimization. An attacker could use this issue to cause SQLite to crash,
resulting in a denial of service, or possibly execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 20.04 LTS:
  libsqlite3-0                    3.31.1-4ubuntu0.2
  sqlite3                         3.31.1-4ubuntu0.2

In general, a standard system update will make all the necessary changes.
