Mandrake Linux Advisory: pam, snort

Apr 29, 2003, 14:25 (0 Talkback[s])
______________________________________________________________________
                Mandrake Linux Security Update Advisory
______________________________________________________________________
Package name:           pam
Advisory ID:            MDKSA-2003:017-1
Date:                   April 28th, 2003
Original Advisory Date: February 18th, 2003
Affected versions:      8.2, 9.0, Corporate Server 2.1,
                        Multi Network Firewall 8.2
______________________________________________________________________
Problem Description:
 Andreas Beck discovered that the pam_xauth module would forward
 authorization information from the root account to unprivileged users.  
 This can be exploited by a local attacker to gain access to the root 
 user's X session.  In order for it to be successfully exploited, the 
 attacker would have to somehow get the root user to su to the account 
 belonging to the attacker.
  
Update:
 The previous fix was incorrect because certain applications, such as
 userdrake and net_monitor could not be executed as root, although they
 could be executed as users who successfully authenticated as root.

To upgrade automatically, use MandrakeUpdate.  The verification of md5
checksums and GPG signatures is performed automatically for you.
If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm".  A list of
FTP mirrors can be obtained from:
  http://www.mandrakesecure.net/en/ftp.php
Please verify the update prior to upgrading to ensure the integrity of
the downloaded package.  You can do this with the command:
  rpm --checksig <filename>
All packages are signed by MandrakeSoft for security.  You can obtain
the GPG public key of the Mandrake Linux Security Team from:

Problem Description:
 An integer overflow was discovered in the Snort stream4 preprocessor
 by the Sourcefire Vulnerability Research Team. This preprocessor
 (spp_stream4) incorrectly calculates segment size parameters during
 stream reassembly for certainm sequence number ranges.  This can
 lead to an integer overflow that can in turn lead to a heap overflow
 that can be exploited to perform a denial of service (DoS) or even
 remote command excution on the host running Snort.
 
 Disabling the stream4 preprocessor will make Snort invulnerable to
 this attack, and the flaw has been fixed upstream in Snort version
 2.0.  Snort versions 1.8 through 1.9.1 are vulnerable.
