  affected >= 2.4.53, < 2.4.54fixed 2.4.54

  If Apache HTTP Server 2.4.53 is configured to do transformations with mod_sed in contexts where the input to mod_sed may be very large, mod_sed may make excessively large memory allocations and trigger an abort.

  affected < 2.4.54fixed 2.4.54

  In Apache HTTP Server 2.4.53 and earlier, a malicious request to a lua script that calls r:parsebody(0) may cause a denial of service due to no default limit on possible input size.

• CVE-2022-28615CriJun 9, 2022
  affected < 2.4.54fixed 2.4.54

  Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the server can be coerced into such a call, third-party modules or lua scrip

  affected < 2.4.54fixed 2.4.54

  The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with mod_luas r:puts() function. Modules compiled and distributed separately from

  affected < 2.4.54fixed 2.4.54

  affected < 2.4.54fixed 2.4.54

  Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.

• CVE-2022-23943CriMar 14, 2022
  affected < 2.4.53fixed 2.4.53

• CVE-2022-22721CriMar 14, 2022
  affected < 2.4.53fixed 2.4.53

  If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server 2.4.52 and earlier.

• CVE-2022-22720CriMar 14, 2022
  affected < 2.4.53fixed 2.4.53

• CVE-2021-42013CriKEVOct 7, 2021
  affected >= 2.4.49, < 2.4.50fixed 2.4.50

  It was found that the fix for CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by t
