A vulnerability was found in FreeRDP where all clients using the /video command line switch might read uninitialized data, decode it as audio/video and display the result, leading to information disclosure.
An out-of-bounds read vulnerability was found in the ZGFX decoder component of FreeRDP. A malicious server can trick a FreeRDP based client to read out-of-bound data and try to decode it. This will result in a crash, causing a denial of service.
An out-of-bounds read vulnerability was discovered in FreeRDP due to missing a range check for input offset index in the ZGFX decoder. A malicious server can trick a FreeRDP based client to read out-of-bound data and try to decode it, resulting in a crash.
CWE-125 - Out-of-bounds ReadA division-by-zero issue was found in FreeRDP's libusb_udevice.c in the urbdrc channel. This flaw exists due to missing input validation in the urbdrc channel. A malicious server can pass specially crafted data to the client, causing a crash and denial of service.
An out-of-bound read vulnerability was discovered in FreeRDP due to improper input length validation in client/data_transfer.c in the urbdrc channel. A malicious server can trigger an out-of-bounds read by tricking a FreeRDP based client to read out-of-bound data and send it back to the server.
CWE-125 - Out-of-bounds ReadAn out-of-bounds read vulnerability exists due to a boundary condition within the urbdrc channel. Attempting an integer addition on narrow types leads to the allocation of a buffer too small to hold the data written. A malicious server can trick a FreeRDP based client to read out-of-bound data and send it back to the server.
CWE-125 - Out-of-bounds ReadA directory traversal issue was discovered in FreeRDP. The vulnerability exists due to missing path canonicalization and base path check for the drive channel. A malicious server can trick a FreeRDP based client to read files outside of the shared directory. This issue allows an attacker to gain access to sensitive information.
An out-of-bounds read vulnerability was discovered in FreeRDP due to improper input length validation in the drive channel. A malicious server can trick a FreeRDP based client to read out-of-bound data and send it back to the server.
CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer{

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.

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.
