Description

In PHP through 5.6.33, 7.0.x before 7.0.28, 7.1.x through 7.1.14, and 7.2.x through 7.2.2, there is a stack-based buffer under-read while parsing an HTTP response in the php_stream_url_wrap_http_ex function in ext/standard/http_fopen_wrapper.c. This subsequently results in copying a large string.

Affected products and versions

  • PHP — Up to and including 5.6.33
  • PHP — From 7.0.0 (including) to 7.0.28 (excluding)
  • PHP — From 7.1.0 (including) to 7.1.14 (including)
