GENTOO LINUX SECURITY ANNOUNCEMENT 200304-09
- - ---------------------------------------------------------------------

          PACKAGE : mgetty
          SUMMARY : buffer overflow, insecure spool dir
             DATE : 2003-04-28 10:17 UTC
          EXPLOIT : remote
VERSIONS AFFECTED : =mgetty-1.1.29
              CVE : CAN-2002-1391 CAN-2002-1392

- - ---------------------------------------------------------------------

* 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.

SOLUTION

It is recommended that all Gentoo Linux users who are running
net-dialup/mgetty upgrade to mgetty-1.1.30 as follows:

emerge sync
emerge mgetty
emerge clean
