DOSEMU contains a flaw that may cause the system administrator to permanantly delete vital parts of the file system. The issue is due to the Makefile.main install section not properly defining the $(abs_top_build_dir) variable. Under some installations, this variable may not be defined, leading the install process to "rm -rf $(TMP)" where $(TMP) is defined as /tmp.
Upgrade to version 1.1.99.2 or higher, as it has been reported to fix this
vulnerability. An upgrade is required as there are no known workarounds.
