Several vulnerabilities have been found in the Apache HTTPD server.
Fabrice Perez reported that certain mod_rewrite configurations are prone to an open redirect.
Chamal De Silva discovered that the mod_proxy_ftp module uses uninitialized memory when proxying to a malicious FTP backend.
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.
Felix Wilhelm reported a buffer overflow flaw in the mod_proxy_uwsgi module which could result in information disclosure or potentially remote code execution.
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.
