Description Guilherme de Almeida Suckevicz 2020-04-15 13:45:47 UTC
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.

Comment 2 Robert Scheck 2020-04-15 14:54:42 UTC
Why do I still get auto-Cc-ed for SQLite security flaws? I'm no longer a package maintainer of sqlite2 (for quite some time already), nor am I (co-)maintaining sqlite itself.

This is because you still are the default assignee for the sqlite2 component in Fedora EPEL.

It seems like this issue existed since sqlite-3.25.0, when window function (https://www.sqlite.org/windowfunctions.html)  was added, but it lead to segmentation fault after https://www3.sqlite.org/cgi/src/info/712e47714863a8ed was committed, which could result in denial of service. This commit is a part of sqlite-3.30 release.

Therefore previous versions are not vulnerable to this flaw.
