Vulnerabilities

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

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.

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…

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.
