Stack-based buffer overflow in the parse_identifier function in tgsi_text.c in the TGSI auxiliary module in the Gallium driver in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (out-of-bounds array access and QEMU process crash) via vectors related to parsing properties.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
