Title: Sybase Adaptive Server Enterprise Attrib_Valid Remote Buffer Overflow Vulnerability

Severity: HIGH

Description:

Sybase Adaptive Server is a full SQL relational database management system. It is available for a variety of platforms including Microsoft Windows operating systems.

A remote buffer overflow vulnerability affects Sybase Adaptive Server Enterprise. This issue is due to a failure of the application to properly validate the length of user-supplied strings prior to copying them into static process buffers.

The buffer overflow affects the 'attrib_valid' Transact-SQL extension function; the affected function is supported to facilitate the manipulation of data types within the database. Apparently the affected function contains a stack-based buffer overflow.

An attacker may exploit this issue to execute arbitrary code with the privileges of the affected application. This may facilitate unauthorized access or privilege escalation.

The issue outlined in this BID was previously presented in BID 12080 (Sybase Adaptive Server Enterprise Multiple Vulnerabilities) along with other issues; each issue is being assigned its own BID. This BID 12080 is being retired.
