Name of the Vulnerable Software and Affected Versions sendmail versions 5.59 through 5.65

Description The issue allows local users to gain root privileges by modifying the IFS variable and passing crafted values to the -oR option. This is due to the use of popen to process a forwarding host argument in SunOS sendmail.
