Comment 4 Marco Benatto 2020-01-31 19:01:43 UTC
There's an issue with sqlite when using SELECT statments on tables or view which names are like shadow table's name.
This issue makes the sqlite application to crash, causing Deny of Service. Availability impact is rated as high due to the crashing while there's no integrality or confidentialy impact as the attacker cannot alter data ou expose data via this flaw.
