iDEFENSE discovered a buffer overflow vulnerability in the ELF format
parsing of the "file" command, one which can be used to execute
arbitrary code with the privileges of the user running the command. The
vulnerability can be exploited by crafting a special ELF binary which is
then input to file. This could be accomplished by leaving the binary on
the file system and waiting for someone to use file to identify it, or
by passing it to a service that uses file to classify input. (For
example, some printer filters run file to determine how to process input
going to a printer.)
