Id Description
2851 Sybase ASE Password Array Heap Overflow

A remote heap overflow exists in Sybase ASE server 12.5. The data structure sent to the server to provide authentication details consists of sets of (data length, data) pairs. By providing a valid username and password, but incorrect field length values, a section of the heap can be overflowed. With a specially crafted request, an attacker can cause a denial of service requiring a restart of the whole ASE process under Windows, or a single server process under Linux. It is reported that this vulnerability could be used to execute arbitrary code, but no exploit code has been released.
