SuSE Security Announcement
Package: tnef < 0-124
Date: Mon Jul 10 19:19:16 CEST 2000
Affected SuSE versions: 6.3-6.4
Vulnerability Type: remote compromise
SuSE default package: no
Other affected systems: all unix systems using this package
A security hole was discovered in the package mentioned above.
Please update it as soon as possible or disable the service if you
are using this software on your SuSE Linux installation(s).
Other Linux distributions or operating systems might be affected
as well, please contact your vendor for information about this
issue.
Please note that we provide this information on an “as-is” basis
only. There is no warranty whatsoever and no liability for any
direct, indirect or incidental damage arising from this information
or the installation of the update package.
1. Problem Description
Tnef extracts eMails compressed with MS-Outlook. The compressed
file includes the path name to which the decompressed data should
be written.
2. Impact
By specifing a path name like /etc/passwd and sending a
compressed mail to root an adversary could gain remote root access
to a system by overwriting the local password database. The same
could happen if a mail virus scanner, like AMaVIS, process’ a
malicious mail.
3. Solution
Update the package from our FTP server.
It’s also possible to use the ‘-x’ option of tnef to specify the
outputfile.
Please verify these md5 checksums of the updates before
installing:
