Huawei NIP6800 versions V500R001C30 and V500R001C60SPC500; and Secospace USG6600 and USG9500 versions V500R001C30SPC200, V500R001C30SPC600, and V500R001C60SPC500 have a vulnerability that the IPSec module handles a message improperly. Attackers can send specific message to cause double free memory. This may compromise normal service.
