CVE-2016-20040: TiEmu 3.03-nogdb+dfsg-3 Buffer Overflow via ROM Parameter

Security readout for executives and security teams

TiEmu 3.03 / 3.03-nogdb+dfsg-3 is reported to have a local buffer overflow in handling the ROM command-line parameter. A local attacker who can supply an oversized ROM parameter may crash the application or potentially execute code. The bundle does not support active exploitation in the wild. Exposure is most likely limited to local systems where TiEmu 3.03 or the 3.03-nogdb+dfsg-3 package is installed and where untrusted users or workflows can influence the ROM parameter passed to the tiemu CLI. This is not described as a remote network-service vulnerability in the supplied bundle. Prioritize remediation for shared Linux desktops, lab systems, CI images, or other environments where local users or automated workflows can invoke TiEmu with attacker-controlled ROM parameters. Lower priority for isolated single-user systems where TiEmu is absent or not exposed to untrusted inputs. Mitigation focus: Inventory systems for TiEmu / Texas Instrument Emulator 3.03 and the 3.03-nogdb+dfsg-3 package.; Remove TiEmu where it is not required, especially from multi-user or shared environments.; Do not pass ROM paths or ROM-related parameters from untrusted input to the tiemu CLI..
