code. This issue only affected Ubuntu 14.04 LTS. (CVE-2013-7443)

Michal Zalewski discovered that SQLite incorrectly handled dequoting of
collation-sequence names. An attacker could use this issue to cause

Michal Zalewski discovered that SQLite incorrectly handle printf precision
and width values during floating-point conversions. An attacker could use
this issue to cause applications using SQLite to crash, resulting in a

Update instructions:

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

Ubuntu 15.04:
  libsqlite3-0                    3.8.7.4-1ubuntu0.1

Ubuntu 14.04 LTS:
