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
