A flaw was found in BusyBox dpkg. The write_status_file() function does not reset a field cursor between package stanzas. When two packages are removed in a single invocation and the first stanza is larger than the second, the second package stanza can be dropped from the status file, causing limited data corruption.

Solution

No solution given by the vendor.


Workaround

Do not use BusyBox dpkg for package management on systems where package integrity is critical. Remove packages one at a time if BusyBox dpkg must be used. Upstream should reset field_start at the beginning of each stanza iteration in write_status_file().
