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.
