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 configurations

• php php (<= 5.5.30) • php php 5.6.0 • php php 5.6.1 • php php 5.6.2 • php php 5.6.3 • php php 5.6.4 • php php 5.6.5 • php php 5.6.6 • php php 5.6.7 • php php 5.6.8 • php php 5.6.9 • php php 5.6.10 • php php 5.6.11 • php php 5.6.12 • php php 5.6.13 • php php 5.6.14 • php php 5.6.15 • php php 5.6.16 • php php 7.0.0 • php php 7.0.1
