Summary

Multiple buffer overflows in the JAR file administration routines in the BSU JAVA subcomponent in IBM DB2 8 before FP16, 9.1 before FP4a, and 9.5 before FP1 allow remote authenticated users to cause a denial of service (instance crash) via a call to the (1) RECOVERJAR or (2) REMOVE_JAR procedure with a crafted parameter, related to (a) sqlj.install_jar and (b) sqlj.replace_jar. http://www-1.ibm.com/support/docview.wss?uid=swg21255572http://www-1.ibm.com/support/docview.wss?uid=swg21287889 http://www-1.ibm.com/support/docview.wss?uid=swg21256235

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

"The installation of IBM DB2 9.5 running on the remote host does not
have any Fix Packs applied. It is, therefore, affected by one or more
of the following issues :

  - There is a security vulnerability in the 'NNSTAT'
    procedure on Windows platforms only that allows low-
    privileged users to overwrite arbitrary files.
    (IZ10776)

  - There is a security vulnerability in the
    'SYSPROC.ADMIN_SP_C' procedure on Windows platforms 
    that allows users to load arbitrary library and 
    execute arbitrary code in the system. (IZ10917)

  - An unspecified vulnerability affects 'DB2WATCH' and
    'DB2FREEZE' on Solaris platforms. (IZ12994)

  - An authenticated, remote user can cause the DB2 instance
    to crash by passing specially crafted parameters to 
    the 'RECOVERJAR' and 'REMOVE_JAR' procedures. (IZ15496)

  - There is an internal buffer overflow vulnerability in
    the DAS process that could allow arbitrary code 
    execution on the affected host. (IZ12406)

  - A local attacker can create arbitrary files as root 
    on Unix and Linux platforms using symlinks to the 
    'dasRecoveryIndex', 'dasRecoveryIndex.tmp', 
    '.dasRecoveryIndex.lock', and 'dasRecoveryIndex.cor' 
    files during initialization. (IZ12798)

  - There are possible buffer overflows involving 'XQUERY', 
    'XMLQUERY', 'XMLEXISTS', and 'XMLTABLE'. (IZ18431)

  - There is a security vulnerability related to a 
    failure to switch the owner of the 'db2fmp' process
    affecting Unix and Linux platforms. (IZ19155)

  - When a memory dump occurs, the password used to connect
    to the database remains visible in plaintext in the 
    memory dump file. (JR28314)

  - The CLR stored procedure deployment feature of IBM 
    Database Add-Ins for Visual Studio can be used to
    escalate privileges or launch a denial of service
    attack against a DB2 server. (JR28431)

  - A flaw exists in the db2ls command that allows a local
    attacker to write to any file on the system through the
    use of symbolic links. Note that this issue does not
    affect Windows systems. (IZ14939)");
