Multiple vulnerabilities in IBM DB2 UDB 8 before Fixpak 15 and 9.1 before Fixpak 3 allow local users to create arbitrary files via (1) unspecified vectors where an attacker's umask is honored, (2) /etc/ld.so.preload, (3) certain "cron data file locations", and other unspecified vectors possibly involving the (4) OSSEMEMDBG or (5) TRC_LOG_FILE environment variable in db2licd (db2licm).
This is a vulnerability exploitable with only local access requires the attacker to have either
physical access to the vulnerable system or a local (shell) account. Examples of locally
exploitable vulnerabilities are peripheral attacks such as Firewire/USB DMA attacks, and
local privilege escalations (e.g., sudo).
The access conditions are somewhat specialized; the following are examples:
The attacking party is limited to a group of systems or users at some level of authorization, possibly untrusted.
Some information must be gathered before a successful attack can be launched.
The affected configuration is non-default, and is not commonly configured (e.g., a vulnerability present when a
server performs user account authentication via a specific scheme, but not present for another authentication scheme).
The attack requires a small amount of social engineering that might occasionally fool cautious users (e.g.,
phishing attacks that modify a web browser’s status bar to show a false link, having to be on someone’s “buddy”
list before sending an IM exploit).
Authentication is not required to access and exploit the vulnerability.
There is no impact to the confidentiality of the system.
Modification of some system files or information is possible, but the attacker does not
have control over what can be modified, or the scope of what the attacker can affect is
limited. For example, system or application files may be overwritten or modified, but
either the attacker has no control over which files are affected or the attacker can
modify files within only a limited context or scope.
There is no impact to the availability of the system.
