Vulnerability from variot

Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. Multiple HTTP/2 implementations are vulnerable to a variety of denial-of-service (DoS) attacks. Apple SwiftNIO and Apache Traffic Server Used in HTTP/2 Contains a resource exhaustion vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. HTTP/2 is the second version of the hypertext transfer protocol, which is mainly used to ensure the communication between the client and the server. A resource management error vulnerability exists in HTTP/2. 8) - aarch64, noarch, ppc64le, s390x, x86_64

CVE-2019-9517

Jonathan Looney reported that a malicious client could perform a
denial of service attack (exhausting h2 workers) by flooding a
connection with requests and basically never reading responses on
the TCP connection.

CVE-2019-10081

Craig Young reported that HTTP/2 PUSHes could lead to an overwrite
of memory in the pushing request's pool, leading to crashes.

CVE-2019-10082

Craig Young reported that the HTTP/2 session handling could be made
to read memory after being freed, during connection shutdown.

CVE-2019-10092

Matei "Mal" Badanoiu reported a limited cross-site scripting
vulnerability in the mod_proxy error page.

CVE-2019-10097

Daniel McCarney reported that 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. The
issue does not affect the stretch release.

CVE-2019-10098

Yukitsugu Sasaki reported a potential open redirect vulnerability in
the mod_rewrite module.

For the oldstable distribution (stretch), these problems have been fixed in version 2.4.25-3+deb9u8.

For the stable distribution (buster), these problems have been fixed in version 2.4.38-3+deb10u1.

We recommend that you upgrade your apache2 packages.
