NetWinder security advisory
ID2000-010
Issued2000-Jul-04
Packageman
SummaryInsecure /tmp files in man
CategoryInsecure temporary file creation
SeverityLow (local privilege escalation)
ProductsDeveloper dm-3.1-15 and earlier
OfficeServer os-1.5-4 and earlier

DESCRIPTION

The "makewhatis" command, a part of the "man" package, creates predictable files in the /tmp directory during its execution. A malicious local user could gain elevated privileges (gid man) by guessing the filenames before they are created.

SOLUTION

Download the following RPM packages to the NetWinder into a temporary directory, then install them with the command "rpm -Uvh *.rpm". Be sure there are no other files ending in ".rpm" in the temporary directory. See http://www.netwinder.org/security/install.html for more help.
