Vulnerabilidad de lectura fuera de límites en mod_macro del servidor Apache HTTP. Este problema afecta al servidor Apache HTTP: hasta 2.4.57. A flaw was found in the mod_macro module of httpd. When processing a very long macro, the null byte terminator will not be added, leading to an out-of-bounds read, resulting in a crash. • https://httpd.apache.org/security/vulnerabilities_24.html • CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2023-45802 – Apache HTTP Server: HTTP/2 stream memory not reclaimed right away on RST
https://notcve.org/view.php?id=CVE-2023-45802
23 Oct 2023 — When a HTTP/2 stream was reset (RST frame) by a client, there was a time window were the request's memory resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A client could send new requests and resets, keeping the connection busy and open and causing the memory footprint to keep on growing. On connection close, all resources were reclaimed, but the process might run out of memory before that.

17 Jan 2023 — Prior to Apache HTTP Server 2.4.55, a malicious backend can cause the response headers to be truncated early, resulting in some headers being incorporated into the response body. If the later headers have any security purpose, they will not be interpreted by the client. A flaw was found in the mod_proxy module of httpd.

17 Jan 2023 — A carefully crafted If: request header can cause a memory read, or write of a single zero byte, in a pool (heap) memory location beyond the header value sent. This could cause the process to crash. This issue affects Apache HTTP Server 2.4.54 and earlier. A flaw was found in the mod_dav module of httpd.
