Critical
| 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 5.5.38
PHP versions 5.6.x prior to 5.6.24
PHP versions 7.x prior to 7.0.9
xmlrpc-epi versions through 0.54.2
Description
The issue is caused by an integer signedness error in the
simplestring addn function, leading to a heap-based buffer overflow. This can be exploited by a remote attacker, potentially allowing them to execute arbitrary code or cause a denial of service.Recommendations
For PHP versions prior to 5.5.38, update to version 5.5.38 or later.
For PHP versions 5.6.x prior to 5.6.24, update to version 5.6.24 or later.
For PHP versions 7.x prior to 7.0.9, update to version 7.0.9 or later.
For xmlrpc-epi versions through 0.54.2, update to a version later than 0.54.2.
As a temporary workaround, consider restricting access to the
simplestring addn function in the xmlrpc-epi module until a patch is available.Exploit
