Name of the Vulnerable Software and Affected Versions HHVM versions prior to 3.30.12 HHVM versions 4.0.0 through 4.8.5 HHVM versions 4.9.0 through 4.23.1 HHVM versions 4.24.0 through 4.28.1

Description The issue is caused by insufficient boundary checks when processing a string in the mb ereg replace function, allowing access to out-of-bounds memory.

Recommendations For HHVM versions prior to 3.30.12, update to version 3.30.12 or later. For HHVM versions 4.0.0 through 4.8.5, update to a version outside of this range. For HHVM versions 4.9.0 through 4.23.1, update to a version outside of this range. For HHVM versions 4.24.0 through 4.28.1, update to a version later than 4.28.1. As a temporary workaround, consider restricting the use of the mb ereg replace function until a patch is available.
