Produktbeschreibung: QEMU ist eine freie Virtualisierungssoftware, die die gesamte Hardware eines Computers emuliert.
Angriff: Ein lokaler Angreifer kann mehrere Schwachstellen in QEMU ausnutzen, um seine Privilegien zu erhöhen oder einen Denial of Service Angriff durchzuführen
Betroffene Betriebssysteme: - Linux
- UNIX
- Windows
Es existiert eine Schwachstelle in QEMU bezüglich des "VirtFS host directory sharing" mittels "Plan 9 File System" (9pfs) beim Zugriff auf Dateien auf einem "shared host directory" und wird durch eine unsachgemäße Zugriffskontrolle verursacht. Ein privilegierter Angreifer in einem Gastsystem kann diese Schwachstelle ausnutzen, um Zugriff auf Dateien auf dem Hostsystem außerhalb des freigegebenen Verzeichnisses zu erlangen und damit seine Privilegien auf dem Host erhöhen.

Es existiert eine Schwachstelle in QEMU, wenn der QEMU Emulator mit "Cirrus CLGD 54xx" Unterstützung kompiliert wurde. Die Schwachstelle besteht in den Funktionen "cirrus_bitblt_rop_fwd_transp_xxx" und "cirrus_bitblt_rop_fwd_xxx" in [hw/display/cirrus_vga_rop.h] und wird durch einen "out-of-bounds" Fehler verursacht. Ein privilegierter Angreifer innerhalb des Gast-Systems kann diese Schwachstelle ausnutzen, um einen Denial of Service Zustand herbeizuführen.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

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.
Vulnerability timeline
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.

vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.

Related by attack behaviour
Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
