IBM Spectrum Scale (5.1.0.0 through 5.1.2.8 and 5.1.3.0 through 5.1.5.1) and IBM Elastic Storage System (6.1.0.0 through 6.1.2.4 and 6.1.3.0 through 6.1.4.1) could allow an authenticated user to cause a denial of service through the GUI using a format string attack. IBM X-Force ID: 239539.
The product uses a function that accepts a format string as an argument, but the format string originates from an external source.

When an attacker can modify an externally-controlled format string, this can lead to buffer overflows, denial of service, or data representation problems. It should be noted that in some circumstances, such as internationalization, the set of format strings is externally controlled by design. If the source of these format strings is trusted (e.g. only contained in library files that are only modifiable by the system administrator), then the external control might not itself pose a vulnerability.
