• CVE-2018-8740: avoid a NULL pointer dereference when the sqlite_master schema contains a corrupt CREATE TABLE AS entry

• CVE-2018-8740: avoid a NULL pointer dereference when the sqlite_master schema contains a corrupt CREATE TABLE AS entry

In SQLite through 3.22.0, databases whose schema is corrupted using a CREATE TABLE AS statement could cause a NULL pointer dereference, related to build.c and prepare.c (CVE-2018-8740).

os_unix.c in SQLite before 3.13.0 improperly implements the temporary directory search algorithm, which might allow local users to obtain sensitive information, cause a denial of service (application crash), or have unspecified other impact by leveraging use of the current working directory for temporary files. (CVE-2016-6153) In SQLite through 3.22.0, databases whose schema is corrupted using a CREATE TABLE AS statement could cause a NULL pointer dereference, related to build.c and prepare (CVE-2018-8740)
