NVD Description

Note: Versions mentioned in the description apply only to the upstream keepass2 package and not the keepass2 package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

KeePass versions 2.35 through 2.61.1 fail to validate KDBX header field sizes before memory allocation in the ReadHeaderField function. Attackers can craft a malicious KDBX file declaring excessive header field lengths to trigger allocation of gigabytes of memory, causing the application to consume resources and terminate.
