Multiple stack-based buffer overflows in IBM DB2 9.1 before Fixpak 5 and 9.5 before Fixpak 1 allow remote attackers to cause a denial of service (system outage) via vectors related to (1) use of XQuery to issue statements; the (2) XMLQUERY, (3) XMLEXISTS, and (4) XMLTABLE statements; and the (5) sqlrlaka function.

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)

According to its version, the IBM DB2 server running on the remote host is affected by one or more of the following issues :

  - There is an unspecified security vulnerability     related to a 'DB2FMP' process. (IZ20352)

  - On Windows, the 'DB2FMP' process is running with OS     privileges. (JR30026)

  - 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. (JR28432)

  - The password used to connect to the database can be     seen in plaintext in a memory dump. (JR27422)

  - There is a possible stack variable overrun in     'SQLRLAKA()'. (IZ16346)

  - A local privilege escalation vulnerability via file     creation can result in root-level access. (IZ12735)

  - There are possible buffer overflows involving 'XQUERY',     'XMLQUERY', 'XMLEXISTS', and 'XMLTABLE'. (IZ18434)

  - A specially crafted client CONNECT request could     crash the server. (IZ07299)

  - There is an unspecified remote buffer overflow in     DAS server code. (IZ22188)

  - INSTALL_JAR can be used to create or overwrite     critical system files. (IZ21983)

According to its version, the installation of IBM DB2 on the remote host is affected by one or more of the following vulnerabilities : 

  - There is an unspecified security vulnerability related to a 'DB2FMP' process (IZ20352).
  - There is an unspecified security vulnerability in a CLR-stored procedure deployment from IBM Database Add-Ins for Visual Studio (JR28432).
  - The password used to connect to the database can be seen in plaintext in a memory dump (JR27422).
  - There is a possible stack variable overrun in 'SQLRLAKA()' (IZ16346).
  - A local privilege escalation vulnerability via file creation can result in root-level access (IZ12735).
  - There are possible buffer overflows involving 'XQUERY',  'XMLQUERY', 'XMLEXISTS', and 'XMLTABLE' (IZ18434).
