NetWinder security advisory
ID2000-001
Issued2000-Feb-26
Updated2000-Jun-25
Packageman
SummaryA buffer overflow in man
CategoryBuffer overflow
SeverityLow (local setgid vulnerability)
ProductsDeveloper dm-3.1-15 and earlier
OfficeServer os-1.5-4 and earlier

DESCRIPTION

A buffer overflow in the "man" package has been found. As a result of this bug, a local user could gain effective gid of "man" by manipulating the MANPATH environment variable. After doing so, the user could alter system manual pages to execute arbitrary code.

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.
