IBM has patched some serious flaws affecting users of DB2 Universal Database version 9.1 that could be exploited locally by attackers.
A vulnerability in several set-uid DB2 binaries allows a user to write to any file on the system through the use of symbolic links.
In addition, local exploitation of another flaw could allow an attacker to elevate privileges to root.
The flaws were reported to IBM last November, said iDefense researcher Greg MacManus Sr.
“The threat should be fairly limited given that this vulnerability will not allow a remote attacker to access the system; however, if an attacker gained local access they would have no problem getting root,” he said.
According to IBM, there is no workaround for either vulnerability—though the company has issued fixes in DB2 version 9.1 FixPak 2.
The same vulnerabilities exist in DB2 Universal Database Version 8. A fix will be available in DB2 UDB Version 8.1 FixPak 15, which is tentatively scheduled to be released in April, according to a statement posted by IBM. The company urged users to contact DB2 Support if a patch is needed prior to the release of FixPak 15.
