With exploit code in circulation and no patch available for a
buffer-overflow bug, Oracle Corp.'s flagship database software is open
to attack, security researchers said today.
The vulnerability was first disclosed yesterday by VeriSign Inc.'s
iDefense Labs, which issued an advisory outlining the flaw in Oracle
Database 10gR2. Earlier versions of the enterprise database software may
also be at risk, iDefense cautioned.
Today, Symantec Corp. followed with a warning to customers of its
DeepSight threat management system. "The issue affects the 'OWNER' and
the 'NAME' parameters of the 'XDB.XDB_PITRIG_PKG.PITRIG_DROP METADATA'
procedure," said Symantec. "Specifically, if the combined length of both
parameters is excessively large, a buffer will overflow when
constructing a SQL query."
An attack requires authentication to the database, but assuming that, a
successful exploit could execute code remotely. Proof-of-concept exploit
code was posted on the Internet last Friday.
Oracle claimed it has quashed the bug in the Database 10g code, but it
will not issue a patch until the next quarterly update -- dubbed
Critical Patch Update, or CPU -- scheduled for Jan. 15, 2008, both
iDefense and Symantec reported.
Because there are no work-arounds available in the interim, Symantec
recommended that users deploy network intrusion-detection systems to
monitor traffic for malicious activity, and allow only trusted employees
to access the database.
