FreeBSD : go -- archive/zip: overflow in preallocation check can cause OOM panic (4ea1082a-1259-11ec-b4fa-dd5a552bdd17)

high Nessus Plugin ID 153220

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

The Go project reports :

An oversight in the previous fix still allows for an OOM panic when the indicated directory size in the archive header is so large that subtracting it from the archive size overflows a uint64, effectively bypassing the check that the number of files in the archive is reasonable.

Solution

Update the affected package.
