Issue Overview:

An HTTP request smuggling vulnerability was found in the mod_proxy_ajp module of httpd. This flaw allows an attacker to smuggle requests to the AJP server, where it forwards requests. (CVE-2022-26377)

An out-of-bounds read vulnerability was found in the mod_isapi module of httpd. The issue occurs when httpd is configured to process requests with the mod_isapi module. (CVE-2022-28330)

An out-of-bounds read vulnerability was found in httpd. A very large input to the ap_rputs and ap_rwrite functions can lead to an integer overflow and result in an out-of-bounds read. (CVE-2022-28614)

An out-of-bounds read vulnerability was found in httpd. A very large input to the ap_strcmp_match function can lead to an integer overflow and result in an out-of-bounds read. (CVE-2022-28615)

A flaw was found in the mod_lua module of httpd. A malicious request to a Lua script that calls parsebody(0) can lead to a denial of service due to no default limit on the possible input size. (CVE-2022-29404)

A flaw was found in the mod_sed module of httpd. A very large input to the mod_sed module can result in a denial of service due to excessively large memory allocations. (CVE-2022-30522)

A flaw was found in the mod_lua module of httpd. The data returned by the wsread function may point past the end of the storage allocated for the buffer, resulting in information disclosure. (CVE-2022-30556)

A flaw was found in the mod_proxy module of httpd. The server may remove the X-Forwarded-* headers from a request based on the client-side Connection header hop-by-hop mechanism. (CVE-2022-31813)
