Description

This security bulletin contains information about 13 secuirty vulnerabilities.

1) Untrusted Pointer Dereference (CVE-ID: CVE-2019-19880)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to invalid pointer dereference in exprListAppendList() function in window.c when processing constant integer values in ORDER BY clauses. A remote attacker with ability to interact with a query can execute arbitrary code on the target system.

2) Input validation error (CVE-ID: CVE-2019-19926)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input within the multiSelect() function in select.c when parsing certain error messages. A remote attacker can perform a denial of service attack.

3) Input validation error (CVE-ID: CVE-2019-19646)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of NOT NULL in an integrity_check PRAGMA command in pragma.c when generating certain columns. A remote attacker can perform a denial of service attack.

4) Infinite loop (CVE-ID: CVE-2019-19645)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in alter.c that can be triggered via certain types of self-referential views in conjunction with ALTER TABLE statements. A remote attacker can consume all available system resources and cause denial of service conditions.

5) Input validation error (CVE-ID: CVE-2019-19603)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input when processing SELECT statements with a nonexistent VIEW. A remote attacker can perform a denial of service attack.

6) Input validation error (CVE-ID: CVE-2019-19317)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input within the lookupName() function in resolve.c, which leads to omitting bits from the colUsed bitmask in the case of a generated column. A remote attacker can perform a denial of service attack.

7) Arbitrary file upload (CVE-ID: CVE-2019-19925)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to zipfileUpdate in "ext/misc/zipfile.c" mishandles a NULL pathname during an update of a ZIP archive. A remote attacker can upload and execute arbitrary file on the server.

8) NULL pointer dereference (CVE-ID: CVE-2019-19923)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to flattenSubquery in "select.c" mishandles certain uses of SELECT DISTINCT involving a LEFT JOIN in which the right-hand side is a view. A remote attacker can cause a NULL pointer dereference and perform a denial of service (DoS) attack.

9) Resource management error (CVE-ID: CVE-2019-19959)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an error when parsing INSERT INTO queries in situations involving embedded '' characters in filenames in ext/misc/zipfile.c in SQLite. A remote attacker can perform a denial of service attack.

10) Memory leak (CVE-ID: CVE-2019-20218)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due memory leak within the selectExpander() function in select.c in SQLite, caused by incorrect exception handling, related to stack unwinding. A remote attacker can trigger with ability to modify the WITH SQL query can gain access to potentially sensitive information.

11) Resource management error (CVE-ID: CVE-2019-19924)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to incorrect error handling in the sqlite3WindowRewrite(), related to parser-tree rewriting in expr.c, vdbeaux.c, and window.c. A remote attacker can use a specially crafted query to perform a denial of service attack.

12) Out-of-bounds write (CVE-ID: CVE-2019-13734)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in SQLite database engine. A remote attacker can pass specially crafted data to the application, trigger out-of-bounds write and execute arbitrary code on the target system.

13) Out-of-bounds read (CVE-ID: CVE-2020-6405)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in SQLite. A remote attacker can pass specially crafted input to the application, trigger out-of-bounds read error and read contents of memory on the system.
