Package : fossil
Version : 1:2.8-1+deb10u1
CVE ID : CVE-2024-24795
Debian Bug : 1070069
Fossil was broken by fixes of CVE-2024-24795 for apache2 package,
and needed an update.
As part of the security fix, the Apache webserver
mod_cgi module has stopped relaying the Content-Length field
of the HTTP reply header from the CGI programs back to the client
in cases where the connection is to be closed and the client
is able to read until end-of-file.
Fossil was fixed by reading the whole input,
re-allocating the input buffer to fit as more input is received,
instead of trusting the CONTENT_LENGTH variable.
For Debian 10 buster, this problem has been fixed in version
1:2.8-1+deb10u1.
We recommend that you upgrade your fossil packages.

Package : apache2
Version : 2.4.59-1~deb10u1
CVE ID : CVE-2019-17567 CVE-2023-31122 CVE-2023-38709 CVE-2023-45802
CVE-2024-24795 CVE-2024-27316
Debian Bug : 1068412
Multiple vulnerabilities have been discovered in the Apache HTTP server,
which may result in HTTP response splitting, denial of service, or
authorization bypass.
CVE-2019-17567
mod_proxy_wstunnel configured on an URL that is not
necessarily Upgraded by the origin server was tunneling
the whole connection regardless, thus allowing for subsequent requests
on the same connection to pass through with no HTTP validation,
authentication or authorization possibly configured.
CVE-2023-31122
An Out-of-bounds Read vulnerability was found in mod_macro.
CVE-2023-38709
A faulty input validation was found in the core of Apache
that allows malicious or exploitable backend/content generators
to split HTTP responses.
CVE-2023-45802
When an HTTP/2 stream was reset (RST frame) by a client, there was a
time window were the request's memory resources were not reclaimed
immediately. Instead, de-allocation was deferred to connection close.
A client could send new requests and resets, keeping the connection
busy and open and causing the memory footprint to keep on growing.
On connection close, all resources were reclaimed, but the process
might run out of memory before that.
CVE-2024-24795
HTTP Response splitting in multiple modules in Apache HTTP Server
allows an attacker that can inject malicious response headers into
backend applications to cause an HTTP desynchronization attack.
CVE-2024-27316
HTTP/2 incoming headers exceeding the limit are temporarily
buffered in nghttp2 in order to generate an informative HTTP
413 response. If a client does not stop sending headers, this
leads to memory exhaustion.
For Debian 10 buster, these problems have been fixed in version
2.4.59-1~deb10u1.
Please note that the fix of CVE-2024-24795, may break unrelated
CGI-BIN scripts. As part of the security fix, the Apache webserver
mod_cgi module has stopped relaying the Content-Length field
of the HTTP reply header from the CGI programs back to the client
in cases where the connection is to be closed and the client
is able to read until end-of-file. You may restore legacy
behavior for trusted scripts by adding the following configuration
environment variable to the
Apache configuration, scoped to the entry or
entries in which scripts are being served via CGI,
SetEnv ap_trust_cgilike_cl "yes".
The definitive fix is to read the whole input,
re-allocating the input buffer to fit as more input is received
in CGI-BIN scripts, and and to not trust that
CONTENT_LENGTH variable is always present.
We recommend that you upgrade your apache2 packages.
