SuSE Security Announcement
Package: inn 2.2.2 (and earlier)
Date: Wed Jun 7 12:24:25 MEST 2000
Affected SuSE versions: 6.1-6.4
Vulnerability Type: remote news compromise
SuSE default package: no
Other affected systems: all unix systems using innd 2.x (x < 4)
______________________________________________________________________________
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
The Usenet News server innd does not check the size of a stack buffer,
when verifying 'cancel requests'. This verification is not enabled by
default (s. innd.conf, 'verifycancels' is set to 'fasle').
2. Impact
If the 'verifycancels' option in innd.conf is set to 'true', it will
enable an attacker to remotely execute arbitrary code with the privileges
of user news on the INN server.
3. Solution
Update the package from our FTP server if you use 'verifycancels'
option.
(Pease note, that this option is not recommended by the innd maintainer and
will also be removed in innd 2.4).
______________________________________________________________________________
Please verify these md5 checksums of the updates before installing:
The i386 RPM for 6.1 will be released next week.
(For SuSE 6.0, please use the 6.1 updates)
