NVD Description
Note: Versions mentioned in the description apply only to the upstream xen package and not the xen package as distributed by Debian.
During Xenstore live update the state record for a Xenstore watch with specified watch depth is written with two bytes missing. This results in an inconsistent state when reading the state back in the new Xenstore, causing a crash of Xenstore or wrong Xenstore data.
