Vulnerabilidades

mgetty prior to version 1.2.1 is affected by: Infinite Loop. The impact is: DoS, the program does never terminates. The component is: g3/g32pbm.c. The attack vector is: Local, the user should open a specially crafted file. The fixed version is: 1.2.1.

mgetty prior to 1.2.1 is affected by: out-of-bounds read. The impact is: DoS, the program may crash if the memory is not mapped. The component is: putwhitespan() in g3/pbm2g3.c. The attack vector is: Local, the victim must open a specially crafted file. The fixed version is: 1.2.1.

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 a buffer overflow if long untrusted input can reach it.

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.

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.

An issue was discovered in mgetty before 1.2.1. In contrib/scrts.c, a stack-based buffer overflow can be triggered via a command-line parameter.

An issue was discovered in mgetty before 1.2.1. In fax/faxq-helper.c, the function do_activate() does not properly sanitize shell metacharacters to prevent command injection. It is possible to use the ||, &&, or > characters within a file created by the "faxq-helper activate <jobid>" command.

faxspool in mgetty 1.1.36 allows local users to overwrite arbitrary files via a symlink attack on a /tmp/faxsp.##### temporary file.

faxrunqd.in in mgetty 1.1.28 and earlier allows local users to overwrite files via a symlink attack on JOB files.

cnd.c in mgetty 1.1.28 and earlier does not properly filter non-printable characters and quotes, which may allow remote attackers to execute arbitrary commands via shell metacharacters in (1) caller ID or (2) caller name strings.

faxspool in mgetty before 1.1.29 uses a world-writable spool directory for outgoing faxes, which allows local users to modify fax transmission privileges.

Buffer overflow in cnd-program for mgetty before 1.1.29 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a Caller ID string with a long CallerName argument.

mgetty 1.1.22 allows local users to overwrite arbitrary files via a symlink attack in some configurations.

The faxrunq and faxrunqd in the mgetty package allows local users to create or modify arbitrary files via a symlink attack which creates a symlink in from /var/spool/fax/outgoing/.last_run to the target file.
