Name of the Vulnerable Software and Affected Versions NetBSD versions prior to 5.0.3 FreeBSD (affected versions not specified) Apple Mac OS X (affected versions not specified)

Description The issue is related to multiple integer signedness errors in the netsmb module in the kernel.

For FreeBSD, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
