Oracle Outside In contains exploitable vulnerabilities in Lotus 123 and Microsoft CAB file parsers, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Oracle Outside In is a set of libraries that can decode over 500 different file formats. Originally written by Stellent, Outside In is now part of Oracle. The Oracle Outside In libraries are used by a variety of applications, including Oracle Fusion Middleware, Google Search Appliance, Guidance Encase Forensics, AccessData FTK, and Novell Groupwise.
Outside In fails to properly handle Lotus 123 and Microsoft CAB file data, which are handled on the Windows platform by the libraries vswk6.dll and sccut.dll, respectively. The Linux version of Outside In uses libvs_wk6.so and libsc_ut.so. Other supported platforms may use different file names.The CAB file parser may be used when handling a variety of file formats, including Microsoft OneNote (.onepkg).
By causing an application to process a specially-crafted file with the Oracle Outside In library, a remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the vulnerable application. Depending on what application is using Outside In, this may happen as the result of some user interaction, such as single-clicking on a file, or it may happen with no user interaction at all.
