An issue was discovered in mgetty before 1.2.1. In contrib/next-login/login.c, the command-line parameter username is passed unsanitized to strcpy(), which can cause a stack-based buffer overflow.

This update for mgetty fixes the following issues :

  - CVE-2018-16741: The function do_activate() did not     properly sanitize shell metacharacters to prevent     command injection (bsc#1108752).

  - CVE-2018-16745: The mail_to parameter was not sanitized,     leading to a buffer overflow if long untrusted input     reached it (bsc#1108756).

  - CVE-2018-16744: The mail_to parameter was not sanitized,     leading to command injection if untrusted input reached     reach it (bsc#1108757).

  - CVE-2018-16742: Prevent stack-based buffer overflow that     could have been triggered via a command-line parameter     (bsc#1108762).

  - CVE-2018-16743: The command-line parameter username wsa     passed unsanitized to strcpy(), which could have caused     a stack-based buffer overflow (bsc#1108761).
