The following resulted from a code audit by Greg Shapiro of
Sendmail, Inc. <gshapiro@gshapiro.net>, whose help is greatly
appreciated:
- SECURITY: shed privileges when -C is used on the command line
- SECURITY: add a popen() wrapper to shed privileges when the command
being executed isn't sendmail
- SECURITY: bounce requests or mail referring to addresses containing
bogus characters, to prevent remote attacks
- SECURITY: add some boundary checking in a few places I'd missed
- SECURITY: be paranoid and call sendmail with "--" before
arguments provided remotely to prevent remote attacks
- SECURITY: verify access permissions with lm_access() to prevent
unauthorized file giveaways and overwrites
- SECURITY: be pedantic about list names to prevent nasty operations
- SECURITY: add and begin using lm_safefopen()
