TITLE

Apache HTTP Server buffer overflow vulnerability (CNVD-2021-102386)

DESCRIPTION

A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. The server is fast, reliable, and can be expanded through simple APIs. There is a buffer overflow vulnerability in Apache HTTP Server, which originates from the r:parsebody of the product failing to correctly determine the user boundary. An attacker can use this vulnerability to cause a buffer overflow. Apple is aware of a report that this issue may have been actively exploited. This was addressed with improved input validation. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2022-05-16-2 macOS Monterey 12.4 macOS Monterey 12.4 addresses the following issues.
