Security Bulletin
Summary
SQLite through 3.31.1 allows attackers to cause a denial of service (segmentation fault) via a malformed window-function query because the AggInfo object's initialization is mishandled. Or the ALTER TABLE implementation has a use-after-free, as demonstrated by an ORDER BY clause that belongs to a compound SELECT statement.
Vulnerability Details
CVEID: CVE-2020-11656
DESCRIPTION: SQLite could allow a remote attacker to obtain sensitive information, caused by a use-after-free in the ALTER TABLE implementation. By sending a specially crafted request, a remote attacker could exploit this vulnerability to obtain sensitive information and then use this information to launch further attacks against the affected system.
