2) Out-of-bounds read
EUVDB-ID: #VU18059
Risk: Low
CVSSv3.1: 2 [CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-9936
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected packages.

3) NULL pointer dereference
EUVDB-ID: #VU18060
Risk: Medium
CVSSv3.1: 4.3 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-9937
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe 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.
