Description

This security bulletin contains information about 2 vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2020-13434)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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.



2) Out-of-bounds write (CVE-ID: CVE-2020-15358)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


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.
