CVE-2018-14337: Debian Linux

High severity, CVSS 7.5. EPSS: 1.4% chance of exploitation in the next 30 days.

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.

Affected products

  • Debian Debian Linux: version 9.0 only
  • Mruby Mruby: version 1.4.1 only
