CVE-2019-3557 (GCVE-0-2019-3557)

Vulnerability from cvelistv5 – Published: 2019-01-15 22:00 – Updated: 2024-08-04 19:12
VLAI
Summary
The implementations of streams for bz2 and php://output improperly implemented their readImpl functions, returning -1 consistently. This behavior caused some stream functions, such as stream_get_line, to trigger an out-of-bounds read when operating on such malformed streams. The implementations were updated to return valid values consistently. This affects all supported versions of HHVM (3.30 and 3.27.4 and below).
