Application crash via oversized image-dimension input
Published Mar 21, 2026 · Updated Mar 21, 2026
Buffer overflow in the Resize Image function in Pixarra TwistedBrush Pro Studio 24.06 allows local users to crash the application. The dialog processes a 1,000-character pasted value in either dimension field as image-size input, causing an out-of-bounds write past the intended buffer. Local access to the desktop interface is required, and exploitation terminates the running application without reported data disclosure or modification.
