"value": "The ISO Presentation layer contains a flaw in the handling of specific \nparameters during normal mode negotiation. A missing length check in the\n processing of the encoded presentation data allows an attacker \ncontrolled field with a zero length value to trigger a bounded heap over\n read. This condition occurs before MMS session establishment, a crafted\n TCP/102 connection attempt can trigger the issue. The resulting over \nread causes the process to terminate, leading to a denial of service \ncondition."

"value": "La capa de presentaci\u00f3n ISO contiene una falla en el manejo de par\u00e1metros espec\u00edficos durante la negociaci\u00f3n del modo normal. Una verificaci\u00f3n de longitud faltante en el procesamiento de los datos de presentaci\u00f3n codificados permite que un campo controlado por el atacante con un valor de longitud cero desencadene una lectura excesiva de un mont\u00f3n acotado. Esta condici\u00f3n ocurre antes del establecimiento de la sesi\u00f3n MMS; un intento de conexi\u00f3n TCP/102 manipulado puede desencadenar el problema. La lectura excesiva resultante provoca la terminaci\u00f3n del proceso, lo que lleva a una condici\u00f3n de denegaci\u00f3n de servicio."

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
