NVD Description
Note: Versions mentioned in the description apply only to the upstream mruby package and not the mruby package as distributed by Ubuntu.
The CHECK macro in mrbgems/mruby-sprintf/src/sprintf.c in mruby 1.4.1 contains a signed integer overflow, possibly leading to out-of-bounds memory access because the mrb_str_resize function in string.c does not check for a negative length.
