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.
