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).

This update was imported from the SUSE:SLE-15:Update update project.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An issue was discovered in mgetty before 1.2.1. In fax_notify_mail() in faxrec.c, the mail_to parameter is     not sanitized. It could allow for command injection if untrusted input can reach it, because popen is     used. (CVE-2018-16744)

Note that Nessus relies on the presence of the package as reported by the vendor.

This update for mgetty fixes the following issues :

  - CVE-2018-16741: Fixed a command injection in     fax/faxq-helper.c (boo#1108752)

  - CVE-2018-16742: Stack-based buffer overflow in     contrib/scrts.c triggered via command line parameter     (boo#1108762)

  - CVE-2018-16743: Stack-based buffer overflow with long     username in contrib/next-login/login.c (boo#1108761)

  - CVE-2018-16744: Command injection in faxrec.c     (boo#1108757)

  - CVE-2018-16745: Stack-based buffer overflow in     fax_notify_mail() in faxrec.c (boo#1108756)

  - sets maximum length of a string to prevent buffer     overflow and thus possible command injection

  - The obsolete contrib/scrts.c tool was deleted, which     contained a buffer overflow.
