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

security flaw

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.

security flaw

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

security flaw

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.

security flaw

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.

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.
