Debian Security Advisory DSA-4509-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso

Package : apache2
CVE ID : CVE-2019-9517 CVE-2019-10081 CVE-2019-10082 CVE-2019-10092
CVE-2019-10097 CVE-2019-10098
Several vulnerabilities have been found in the Apache HTTPD server.
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.
