SuSE Security Announcement
Package: mysql < 3.22.30
Date: Fri, 11 Feb 2000 21:54:49 GMT
Affected SuSE versions: all
Vulnerability Type: remote database access
SuSE default package: no
Other affected systems: all unix systems using mysql < 3.22.30
______________________________________________________________________________
A security hole was discovered in the package mentioned above.
Please update 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 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
A bug in the authentication function of mysql allows anyone who knows
a valid username to successfully authenticate as that users in no more
than 32 tries.
2. Impact
Remote users may gain access to the mysql database data.
3. Solution
Update the package from our FTP server.
Please note that it will take some time until rpms for 6.1 are available,
because the security patch does not work on that tree. As a workaround, you
might try the rpm for SuSE 6.2
______________________________________________________________________________
Please verify these md5 checksums of the updates before installing:
(6.1 updates are not available yet. You might try the 6.2 rpm in the meantime.)

Hi Everybody!
Please, can somebody tell me how to verify a md5 checksum?
I read the rpm manpage and it says something about md5 checksums
there, but I don't know how to pass a given checksum to rpm.
In the manpage it says something about a database, but surely
the checksum of an update-package wouldn't be in a database,
would it?
If it were, it wouldn't be provided along with the package now,
would it?
Thanks in advance,
Till Rotter

SuSE Security Announcement
Package: util < 2.10f
Date: Thu Feb 10 20:03:43 CET 2000
Affected SuSE versions: all
Vulnerability Type: (unlikely) local root compromise
SuSE default package: yes
Other affected systems: all linux systems using util < 2.10f
______________________________________________________________________________
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 mount/umount command doesn't do proper bounds checking on user input.
2. Impact
If an attacker executes mount/umount with a long relative pathname, it
will overwrite dynamic allocated memory of the realpath function.
It is possible that an attacker could gain root privileges by modifying
the heap data, however we were not able to exploit it.
3. Solution
Update the package from our FTP server or remove the suid bits.
______________________________________________________________________________
Please verify these md5 checksums of the updates before installing:
(For SuSE 6.0, please use the 6.1 updates)

Hi!
IIRC, there was a small discussion about DeleGate in the past (some
weeks ago, I think). Therefore I decided to forward you this post from
BugTraq.
best regards,

DO NOT USE DELEGATE.
Here are some of my findings with delegate, and I'm still not done yet.
-- snip --
Delegate Problems
=================
Start of access.c:
* Line 41 defines a fixed-length variable (authority - 1024 bytes).
- scan_AUTH() does no bound checking and blindly uses strcat() to
append
to the variable.
* Line 57 defines a fixed-length variable (xauth - 1024 bytes).
- findAuth() does no bounds checking and blindly passes all three
variables to sprintf().
* Line 66 calls sprintf() again to output into a fixed-length variable
(xauth - 1024 bytes).
* Line 74 defines a fixed-length variable (userhost - 256 bytes).
- auth_manager() does no bound checking and blindly passes two
variables
to sprintf() with no bounds checking.
* Line 87 defines a fixed-length variable (auth - 256 bytes).
- auth_anonftp() does no bounds checking and blindly passes the
anonymous FTP password to sprintf().
* Line 116 defines a fixed-length variable (hostb - 256 bytes).
- NotifyPlatform() calls getClientHostPort() which calls
getClientHostPortAddr() blindly copies (strcpy) the address passed
from NotifyPlatform into a 32-byte buffer defined in the
'Connection'
structure.
* Line 145 defines a fixed-length variable (myuri - 256 bytes).
- clientIF_HP() calls _clientIF() which blindly outputs (sprintf) the
host and port information into the variable 'myuri' after receiving
its data from 'myhp'.
* Line 145 defines a fixed-length variable (client - 256 bytes).
- makeForwarded() calls getClientHostPort() which calls
getClientHostPortAddr() which blindly copies (strcpy) the address
passed from NotifyPlatform into a 32-byte buffer defined in the
'Connection' structure.
* Line 146 defines a fixed-length variable (myhp - 256 bytes).
- clientIF_HP() calls _clientIF() which returns data that is not
bound-checked into the variable 'myhp' for latter consumption by
sprintf().
* Line 168 defines a fixed-length variable (atype - 128 bytes).
- makeAuthorization() calls sscanf() to retrieve arguments and cannot
bound check the data resulting in a buffer overrun.
* Line 168 defines a fixed-length variable (afmt - 128 bytes).
- makeAuthorization() calls sscanf() to retrieve arguments and cannot
bound check the data resulting in a buffer overrun.
* Line 169 defines a fixed-length variable (gauth - 256 bytes).
- makeAuthorization() calls strfConn() to return the protocol desired
into 'gauth', and two more strings are appended (strcat) without
bounds checking.
* Line 169 defines a fixed-length variable (eauth - 256 bytes).
- makeAuthorization() calls str_to64() specifying the size as eauth as
512 bytes instead of 256 bytes.
* Line 215 defines a fixed-length variable (host - 256 bytes).
- makeClientLog() does not perform bound checking on the results
returned by strfConn() allowing for a buffer overrun.
* Line 215 defines a fixed-length variable (iuser - 256 bytes).
- makeClientLog() does not perform bound checking on the results
returned by strfConn() allowing for a buffer overrun.
* Line 215 defines a fixed-length variable (auser - 256 bytes).
- makeClientLog() does not perform bound checking on the results
returned by strfConn() allowing for a buffer overrun.
* Line 320 uses strcpy() blindly.
- No bounds checking is performed before copying 'clhost' into
Client_Addr
which is the 32-byte fixed-length variable 'cl_Addr' in the
structure
Connection defined in delegate.h.
* Line 321 uses strcpy() blindly.
- No bounds checking is performed before copying 'clhost' into
Client_Addr
which is the 128-byte fixed-length variable 'cl_Host' in the
structure
Connection defined in delegate.h.
* Line 429 defines a fixed-length variable (buf - 1024 bytes).
- scanIdent() does not perform bounds checking on the variable passed
and blindly copies it (strcpy) into 'buf'. Allows an attacker to
create their own identd trojan/daemon and pass arbitrary code.
* Line 449 defines a fixed-length variable (addrhostport - 256 bytes).
- getClientHostPortAddr() does not perform bounds checking on the
results returned from getpeerName(). Allows an attacker to create
their own fake DNS reply and pass arbitrary code.
* Line 449 defines a fixed-length variable (addr - 256 bytes).
- Suffers from insufficient bounds checking on the result returned by
getpeerName() and receives data from sscanf().
* Line 449 defines a fixed-length variable (host - 256 bytes).
- Suffers from insufficient bounds checking on the result returned by
getpeerName() and receives data from sscanf().
* Line 456 uses strcpy() blindly.
- No bounds checking is performed before copying 'addr' into
Client_Addr
which is the 32-byte fixed-length variable 'cl_Addr' in the
structure
Connection defined in delegate.h.
* Line 457 uses strcpy() blindly.
- No bounds checking is performed before copying 'host' into
Client_Addr
which is the 128-byte fixed-length variable 'cl_Host' in the
structure
Connection defined in delegate.h.
* Line 528 defines a fixed-length variable (host - 1024 bytes).
- No bounds checking is performed on 'hostport' before its blindly
passed into 'host' by sscanf().
* Line 549 defines a fixed-length variable (user - 128 bytes).
- A fixed-length variable is passed to getClientUser0() and it suffers
from insufficient bounds checking noted on line 429.
* Line 584 defines a fixed-length variable (host - 256 bytes).

4 February 2000 IETF Excludes Wiretapping
The Internet Engineering Task Force (IETF) has voted against
incorporating
wiretapping capabilities into the next generation of Internet protocols.
The IETF says that because it is an international standards
organization,
incorporating net wiretapping would subject the rest of the world to US
law. The IETF also expressed concerns that built-in net tapping
capabilities hold the potential for abuse.

Hi,
ok, some details: ping www.ibm.de from that particular system show : host
unknown
but from any other system I get an response.
this is an 3Com Fast Ethernet PCI card in a Firewall (!!?). So I think it
is an (security) problem, or?

Thema: Re: [suse-security] netstat -s
hi,
does not sound like security problem.
sounds like the socket buffer space is too small.
maybe tx/rx queue size on the adapter?
btw, i can ping both sites :)

Hi,
can tell me somebody what that is:
by using: netstat -s
I receive:
TcpExp:
10 packets pruned from receive queue because of socket buffer
overrun
221088 packets dropped from out-of-order queue because of socket
buffer overrun
the problem is I cannot ping www.ibm.de but www.de.ibm.comwww.ibm.de is an alias of www.de.ibm.com

I'm running version 1.9 of the suse firewall and I need to get my VPN
client on a win95 workstation to pass through. If I open everything
with
ipchains, it works. What do I need to change in the rc.firewall to
allow
these vpn (pptp) packets through without compromising my security?
I'm quite ignorant about firewalls, so please give me "der kinder"
version.
Thanks,
DREW.
