Buffer Overflow vulnerability in SunBK201 umicat through v.0.3.2 and fixed in v.0.3.3 allows an attacker to execute arbitrary code via the power(uct_int_t x, uct_int_t n) in src/uct_upstream.c.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
