Description

sapi/fpm/fpm/fpm_log.c in PHP before 5.5.31, 5.6.x before 5.6.17, and 7.x before 7.0.2 misinterprets the semantics of the snprintf return value, which allows attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read and buffer overflow) via a long string, as demonstrated by a long URI in a configuration with custom REQUEST_URI logging.

Affected products and versions

  • PHP — Up to and including 5.5.30
  • PHP versions 5.6.0alpha1, 5.6.0alpha2, 5.6.0alpha3, 5.6.0alpha4, 5.6.0alpha5, 5.6.0beta1, 5.6.0beta2, 5.6.0beta3, 5.6.0beta4, 5.6.1, 5.6.2, 5.6.3, 5.6.4, 5.6.5, 5.6.6, 5.6.7, 5.6.8, 5.6.9, 5.6.10, 5.6.11, 5.6.12, 5.6.13, 5.6.14, 5.6.15, 5.6.16, 7.0.0, 7.0.1
