Description

This security bulletin contains information about 2 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2019-9936)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 2.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


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

The vulnerability exists due to a boundary condition within the fts5HashEntrySort in sqlite3.c when running fts5 prefix queries inside a transaction. A remote user with ability to send queries can trigger heap-based buffer over-read error and read contents of memory on the system.


2) NULL pointer dereference (CVE-ID: CVE-2019-9937)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


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

The vulnerability exists due to a NULL pointer dreference error when processing interleaving reads and writes in a single transaction with an fts5 virtual table in fts5ChunkIterate in sqlite3.c. This is related to ext/fts5/fts5_hash.c and ext/fts5/fts5_index.c. A remote attacker can perform a denial of service (DoS) attack.
