Gert Doering : Security Vulnerabilities, CVEs, CVSS score >= 3

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.

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.
