Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions PHP versions prior to 7.0.4

Description The issue is related to an integer overflow in the xml utf8 encode function, which can cause a heap-based buffer overflow. This can be triggered by a remote attacker using a long argument to the utf8 encode function, potentially leading to a denial of service or other unspecified impacts.

Recommendations For PHP versions prior to 7.0.4, update to version 7.0.4 or later to resolve the issue. As a temporary workaround, consider restricting the use of the utf8 encode function to minimize the risk of exploitation.
