Aliases: CVE-2020-35452 |
Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow |

Affected by 5 other vulnerabilities. |
| Vulnerability | Summary | Aliases |
|---|---|---|
| VCID-3djp-gq4c-1fa9 | A limited cross-site scripting issue was reported affecting the mod_proxy error page. An attacker could cause the link on the error page to be malfomed and instead point to a page of their choice. This would only be exploitable where a server was set up with proxying enabled but was misconfigured in such a way that the Proxy Error page was displayed. We have taken this opportunity to also remove request data from many other in-built error messages. Note however this issue did not affect them directly and their output was already escaped to prevent cross-site scripting attacks. |
CVE-2019-10092
|
| VCID-7vfk-1dwm-xbbt | When mod_remoteip was configured to use a trusted intermediary proxy server using the "PROXY" protocol, a specially crafted PROXY header could trigger a stack buffer overflow or NULL pointer deference. This vulnerability could only be triggered by a trusted proxy and not by untrusted HTTP clients. |
CVE-2019-10097
|
| VCID-a9rw-3s1y-hqd7 | Using fuzzed network input, the http/2 session handling could be made to read memory after being freed, during connection shutdown. |
CVE-2019-10082
|
| VCID-h6kk-81jx-h7b8 | Redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL. |
CVE-2019-10098
|
| VCID-v41h-pbbe-zfas | HTTP/2 very early pushes, for example configured with "H2PushResource", could lead to an overwrite of memory in the pushing request's pool, leading to crashes. The memory copied is that of the configured push link header values, not data supplied by the client. |
CVE-2019-10081
|
| VCID-y3k1-c4rn-xbc2 | A malicious client could perform a DoS attack by flooding a connection with requests and basically never reading responses on the TCP connection. Depending on h2 worker dimensioning, it was possible to block those with relatively few connections. |
