-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Borland InterBase Multiple Buffer Overflow Vulnerabilities http://risesecurity.org/advisory/RISE-2007002/ Published: October 3, 2007 Updated: October 3, 2007 INTRODUCTION There exists multiple vulnerabilities within functions of Borland InterBase, which when properly exploited can lead to remote compromise of the vulnerable system. These vulnerabilities were confirmed by us in the following versions of Borland InterBase, other versions may be also affected. Borland InterBase WI-V8.1.0.257 Borland InterBase WI-V8.0.0.123 Borland InterBase WI-V7.5.1.80 Borland InterBase WI-V7.5.0.129 Borland InterBase WI-V7.0.1.1 Borland InterBase WI-V6.5.0.28 Borland InterBase WI-V6.0.1.6 Borland InterBase WI-O6.0.2.0 Borland InterBase WI-O6.0.1.6 Borland InterBase WI-V6.0.1.0 Borland InterBase WI-V6.0.0.627 Borland InterBase WI-V5.5.0.742 Borland InterBase WI-V5.1.1.680 Borland InterBase LI-V8.1.0.253 Borland InterBase LI-V8.0.0.54 Borland InterBase LI-V8.0.0.53 DETAILS The vulnerable functions do not validate user supplied data when copying it to a stack-based buffer, resulting in a stack-based buffer overflow. The exploitation of these vulnerabilities are trivial and results in remote compromise of the vulnerable system. This is the list of vulnerable functions, some of them contain more than one stack-based buffer overflow vulnerability. 1. INET_connect 2. SVC_attach 3. isc_attach_database 4. jrd8_attach_database 5. isc_create_database 6. jrd8_create_database 7. PWD_db_aliased 8. expand_filename2 9. open_marker_file (UNIX only) These vulnerabilities can be triggered by sending specially crafted attach, create and service attach requests. Proof of concept codes for these vulnerabilities can be downloaded from our website http://risesecurity.org/. VENDOR Vendor was notified, but did not answer to our reports. Proper corrections should be available soon. CREDITS These vulnerabilities were discovered by Adriano Lima and Ramon de Carvalho Valle .
