Description

KeePassXC is a cross-platform community-driven port of the Windows application KeePass Password Safe. Prior to 2.8.0-beta1, KeePass1 / KDB legacy import retains raw Entry pointers in m_entryUuids after deleting metastream entries. When a crafted, unlockable .kdb file contains an earlier metastream entry followed by a KPX_CUSTOM_ICONS_4 metastream that references the earlier UUID, parseCustomIcons4() calls Entry::setIcon through the stale pointer, causing a heap use-after-free with a controlled write and a reliable process crash. This issue is fixed in version 2.8.0-beta1.
