(2) NUMTOYMINTERVAL() function - This function is responsible for handling date conversions. (3) NUMTODSINTERVAL() function - This function is responsible for handling date/time conversions. (4) FROM_TZ() function - This function is responsible for handling time stamp conversions. SOFTWARE: Oracle 9i Database DAMAGE: Execution of arbitrary code or accessing data with privilege of the vulnerable process may occur if vulnerabilities are exploited. Note that Oracle typically runs as System on Windows and as the Oracle user on UNIX. By supplying a very long character string to the vulnerable functions noted above, an unauthorized user could overwrite a return address on the stack, resulting in the ability to execute arbitrary code or access data with the privileges of the vulnerable process. SOLUTION: Upgrade to Oracle 9i Database Release 2, version 9.2.0.3. ______________________________________________________________________________ VULNERABILITY The risk is MEDIUM. An unauthorized user may execute arbitrary ASSESSMENT: code or access data. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/o-093.shtml ORIGINAL BULLETIN: US-CERT Vulnerability Note VU#819126 http://www.kb.cert.org/vuls/id/819126 US-CERT Vulnerability Note VU#240174 http://www.kb.cert.org/vuls/id/240174 US-CERT Vulnerability Note VU#846582 http://www.kb.cert.org/vuls/id/846582 US-CERT Vulnerability Note VU#399806 http://www.kb.cert.org/vuls/id/399806 ADDITIONAL LINK: Oracle Metalink (account required) http://metalink.oracle.com ______________________________________________________________________________ - -----BEGIN PGP SIGNATURE----- Version: 4.0 Business Edition iQCVAwUBQE0OELnzJzdsy3QZAQGDaAQA40YNuyK8M1AELr6GhofBgTknq1DEN9vo siACMODZDhA/miNtO7qW8smXfz6HJbqz53hwBn35k7ATgRQAl81adyy70Aw8WAcJ UyiHS/EpDiK+Tm6Qvu7si60l7xkbvjU0D/T44n22jDvpukq+FNhHi371zWwAvqAN ckCPGi3Q34s= =KyKm - -----END PGP SIGNATURE----- - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
