Mageia: 2020-0327 Moderate: Apache HTTP Server Crash and RCE Issues
mageia
August 18, 2020
Apache HTTP Server versions 2.4.20 to 2.4.43
Summary
Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the
'Cache-Digest' header in a HTTP/2 request would result in a crash when the
server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the
HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched
servers (CVE-2020-9490).
Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and
possible remote code execution (CVE-2020-11984).
Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for
the HTTP/2 module and on certain traffic edge patterns, logging statements were
made on the wrong connection, causing concurrent use of memory pools.
Configuring the LogLevel of mod_http2 above "info" will mitigate this
vulnerability for unpatched servers (CVE-2020-11993).
The apache package has been updated to version 2.4.46, fixing these issues and
other bugs. See the upstream CHANGES file for details.
