Title
Stack Buffer Overflow in ei_s_print_term at Very Large Integer
Summary
Stack-based Buffer Overflow vulnerability in Erlang OTP (erl_interface) allows Stack-based Buffer Overflow. This vulnerability is associated with program file lib/erl_interface/src/misc/ei_printterm.c and program routine ei_s_print_term. The C function ei_s_print_term uses an internal 2000-character stack buffer to format terms. When called with an encoded Erlang term containing a very large integer (encoded representation exceeding 2000 characters), the buffer overflows. The overflow bytes are restricted to the ASCII values of 0-9 and A-F, which limits exploitation to Denial of Service. The companion function ei_print_term, which prints directly to a FILE instead of a memory buffer, does not contain this bug. This issue affects OTP from OTP 17.0 before OTP 29.0.2, OTP 28.5.0.2 and OTP 27.3.4.13, corresponding to erl_interface from 3.7.16 before 5.8.1, 5.7.0.1 and 5.5.2.1.

When called with an encoded Erlang term containing a very large integer (encoded representation exceeding 2000 characters), the buffer overflows. The overflow bytes are restricted to the ASCII values of 0-9 and A-F, which limits exploitation to Denial of Service.\n\nThe companion function ei_print_term, which prints directly to a FILE instead of a memory buffer, does not contain this bug.\n\nThis issue affects OTP from OTP 17.0 before OTP\u00a029.0.2, OTP\u00a028.5.0.2 and OTP\u00a027.3.4.13, corresponding to erl_interface from 3.7.16 before 5.8.1, 5.7.0.1 and 5.5.2.1."
