Package : apache2
CVE ID : CVE-2020-1927 CVE-2020-1934 CVE-2020-9490 CVE-2020-11984
CVE-2020-11993

Several vulnerabilities have been found in the Apache HTTPD server.

CVE-2020-1927

Fabrice Perez reported that certain mod_rewrite configurations are
prone to an open redirect.

CVE-2020-1934

Chamal De Silva discovered that the mod_proxy_ftp module uses
uninitialized memory when proxying to a malicious FTP backend.

CVE-2020-9490

Felix Wilhelm discovered that a specially crafted value for the
'Cache-Digest' header in a HTTP/2 request could cause a crash when
the server actually tries to HTTP/2 PUSH a resource afterwards.

CVE-2020-11984

Felix Wilhelm reported a buffer overflow flaw in the mod_proxy_uwsgi
module which could result in information disclosure or potentially
remote code execution.

CVE-2020-11993

Felix Wilhelm reported that when trace/debug was enabled for the
HTTP/2 module certain traffic edge patterns can cause logging
statements on the wrong connection, causing concurrent use of
memory pools.

For the stable distribution (buster), these problems have been fixed in
version 2.4.38-3+deb10u4.

We recommend that you upgrade your apache2 packages.
