Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-13631)
The vulnerability allows a local user to bypass certain security restrictions.
The vulnerability exists due an error in alter.c and build.c files in SQLite that allows a local user to rename a virtual table into a shadow table. A local user with permissions to create virtual tables can renamed them and gain unauthorized access to the fronted application.
2) Use-after-free (CVE-ID: CVE-2020-13871)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in resetAccumulator() function in select.c. A remote attacker can pass specially crafted data to the application, trigger a use-after-free error and crash the service or execute arbitrary code on the target system
3) Out-of-bounds write (CVE-ID: CVE-2020-15358)
The vulnerability allows a local authenticated user to perform a denial of service (DoS) attack.
In SQLite before 3.32.3, select.c mishandles query-flattener optimization, leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation.
4) NULL pointer dereference (CVE-ID: CVE-2020-13632)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in ext/fts3/fts3_snippet.c in SQLite. A local user can trigger denial of service conditions via a crafted matchinfo() query.
5) Input validation error (CVE-ID: CVE-2020-13435)
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 in sqlite3ExprCodeTarget() function in expr.c. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
6) Integer overflow (CVE-ID: CVE-2020-13434)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow within the sqlite3_str_vappendf() function in printf.c. A remote attacker can pass specially crafted data to the application, trigger integer overflow and crash the application.
7) Use-after-free (CVE-ID: CVE-2020-13630)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the fts3EvalNextRow() function in ext/fts3/fts3.c. A remote attacker can pass specially crafted data to application, trigger a use-after-free error and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
