A vulnerability, which was classified as critical, was found in rizinorg rizin up to 0.8.0. This affects the function rz_utf8_encode in the library /librz/util/utf8.c. The manipulation leads to heap-based buffer overflow. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue.
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.
