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

  • A local user may be able to overwrite arbitrary files, create arbitrary world-writeable directories, or gain root privileges via symlink attacks or specially crafted environment variables. (IY98210 / IY99261)

  • A user may be able to continue to execute a method even once privileges for the method have been revoked.
    (IY88226, version 8 only)

  • There is an unspecified issue allowing for privilege elevation when DB2 ‘execs’ executables while running as root. (IY98206 / IY98176)

  • There is an unspecified vulnerability related to incorrect authorization routines. (JR25940, version 8 only)

  • There is an unspecified vulnerability in ‘AUTH_LIST_GROUPS_FOR_AUTHID’. (IZ01828, version 9.1 only)

  • There is an unspecified vulnerability in the ‘db2licm’ and ‘db2pd’ tools. (IY97922 / IY97936)

  • There is an unspecified vulnerability involving ‘db2licd’ and the ‘OSSEMEMDBG’ and ‘TRC_LOG_FILE’ environment variables. (IY98011 / IY98101)

  • There is a buffer overflow involving the ‘DASPROF’ environment variable. (IY97346 / IY99311)

  • There is an unspecified vulnerability that can arise during instance and FMP startup. (IZ01923 / IZ02067)

  • The DB2JDS service may allow for arbitrary code execution without the need for authentication due to a stack overflow in an internal sprintf() call.
    (IY97750, version 8 only)

  • The DB2JDS service is affected by two denial of service issues that can be triggered by packets with an invalid LANG parameter or a long packet, which cause the process to terminate (version 8 only).

Note that there is currently insufficient information to determine to what extent the first set of issues overlaps the others.
