Integer overflow in the load_iface function in Tools/gdomap.c in
gdomap in GNUstep Base before 1.20.0 might allow context-dependent
attackers to execute arbitrary code via a (1) file or (2) socket that
provides configuration data with many entries, leading to a heap-based
buffer overflow.

Tools/gdomap.c in gdomap in GNUstep Base before 1.20.0 allows local
users to read arbitrary files via a (1) -c or (2) -a option, which
prints file contents in an error message.


Please note that CVE-2010-1457 is only exploitable if gdomap is installed suid root (it is not in Fedora).  The impact of CVE-2010-1620 may be minor as well since arbitrary code would be executed as the user calling it, however gdomap seems to be able to run as a daemon as well (although we do not provide an initscript of any sort it looks like), and due to the ports it wants to bind to (UDP or TCP 538), would imply being run as root.  So while there may be very little chance of there being a scenario where this might be exploited, upstream has corrected this in the 1.20.0 release and it would be worth updating to.

It looks like the fix for CVE-2010-1620 is here:
