Local access is required to approach this attack. Moreover, an exploit is present. Detailsinfo A vulnerability was found in ticalc Texas Instrument Emulator 3.03 and classified as critical. Affected by this issue is an unknown code of the component Command-Line Interface. The manipulation of the argument ROM with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. CVE summarizes: TiEmu 3.03-nogdb+dfsg-3 contains a buffer overflow vulnerability in the ROM parameter handling that allows local attackers to crash the application or execute arbitrary code. Attackers can supply an oversized ROM parameter to the tiemu command-line interface to overflow the stack buffer and overwrite the instruction pointer with malicious addresses.
