Source: crossroads
Version: 2.81-2
Severity: serious
Tags: security

crossroads's xr/Makefile has:

| $(BINDIR)/xr: $(BIN)
| 	cp $(BIN) $(TMPXR)
| 	install $(TMPXR) $(BINDIR)/xr
| 	rm -f $(TMPXR)

where

| TMPXR         = /tmp/xr-$(shell whoami)

Jakub Wilk observed that a malicious user could create /tmp/xr-root as a
directory with mode 777 and replace the directory with an arbitrary file
after the cp (via inotify) thus injecting an arbitrary binary into the
build.
