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
    FIXED VERSION : >=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
