Security update for rmt-server
This update for rmt-server fixes the following issues:
Update to version 2.6.5:
- Solved potential bug of SCC repository URLs changing over time. RMT now self heals by removing the previous invalid repository and creating the correct one.
- Add web server settings to /etc/rmt.conf: Now it's possible to configure the minimum and maximum threads count as well the number of web server workers to be booted through /etc/rmt.conf.
- Instead of using an MD5 of URLs for custom repository friendly_ids, RMT now builds an ID from the name.
- Fix RMT file caching based on timestamps: Previously, RMT sent GET requests with the header 'If-Modified-Since' to a repository server and if the response had a 304 (Not Modified), it would copy a file from the local cache instead of downloading. However, if the local file timestamp accidentally changed to a date newer than the one on the repository server, RMT would have an outdated file, which caused some errors. Now, RMT makes HEAD requests to the repositories servers and inspect the 'Last-Modified' header to decide whether to download a file or copy it from cache, by comparing the equalness of timestamps.
- Fixed an issue where relative paths supplied to
rmt-cli import reposcaused the command to fail. - Friendlier IDs for custom repositories:
In an effort to simplify the handling of SCC and custom repositories,
RMT now has friendly IDs. For SCC repositories, it's the same SCC ID
as before. For custom repositories, it can either be user provided
or RMT generated (MD5 of the provided URL).
Benefits:
rmt-cli mirror repositoriesnow works for custom repositories.- Custom repository IDs can be the same across RMT instances.
- No more confusing 'SCC ID' vs 'ID' in
rmt-clioutput. Deprecation Warnings: - RMT now uses a different ID for custom repositories than before. RMT still supports that old ID, but it's recommended to start using the new ID to ensure future compatibility.
- Updated rails and puma dependencies for security fixes.

Описание
In Puma before versions 3.12.2 and 4.3.1, a poorly-behaved client could use keepalive requests to monopolize Puma's reactor and create a denial of service attack. If more keepalive connections to Puma are opened than there are threads available, additional connections will wait permanently if the attacker sends requests frequently enough. This vulnerability is patched in Puma 4.3.1 and 3.12.2.

A remote code execution vulnerability in development mode Rails <5.2.2.1, <6.0.0.beta3 can allow an attacker to guess the automatically generated development mode secret token. This secret token can be used in combination with other Rails internals to escalate to a remote code execution exploit.

In Puma (RubyGem) before 4.3.4 and 3.12.5, an attacker could smuggle an HTTP response, by using an invalid transfer-encoding header. The problem has been fixed in Puma 3.12.5 and Puma 4.3.4.

Описание
In Puma (RubyGem) before 4.3.5 and 3.12.6, a client could smuggle a request through a proxy, causing the proxy to send a response back to another unknown client. If the proxy uses persistent connections and the client adds another request in via HTTP pipelining, the proxy may mistake it as the first request's body. Puma, however, would see it as two requests, and when processing the second request, send back a response that the proxy does not expect. If the proxy has reused the persistent connection to Puma to send another request for a different client, the second response from the first client will be sent to the second client. This is a similar but different vulnerability from CVE-2020-11076. The problem has been fixed in Puma 3.12.6 and Puma 4.3.5.

Описание
In Action View before versions 5.2.4.4 and 6.0.3.3 there is a potential Cross-Site Scripting (XSS) vulnerability in Action View's translation helpers. Views that allow the user to control the default (not found) value of the `t` and `translate` helpers could be susceptible to XSS attacks. When an HTML-unsafe string is passed as the default for a missing translation key named html or ending in _html, the default string is incorrectly marked as HTML-safe and not escaped. This is patched in versions 6.0.3.3 and 5.2.4.4. A workaround without upgrading is proposed in the source advisory.

Описание
In Puma (RubyGem) before 4.3.2 and before 3.12.3, if an application using Puma allows untrusted input in a response header, an attacker can use newline characters (i.e. `CR`, `LF` or`/r`, `/n`) to end the header and inject malicious content, such as additional headers or an entirely new response body. This vulnerability is known as HTTP Response Splitting. While not an attack in itself, response splitting is a vector for several other attacks, such as cross-site scripting (XSS). This is related to CVE-2019-16254, which fixed this vulnerability for the WEBrick Ruby web server. This has been fixed in versions 4.3.2 and 3.12.3 by checking all headers for line endings and rejecting headers with those characters.

In Puma (RubyGem) before 4.3.3 and 3.12.4, if an application using Puma allows untrusted input in an early-hints header, an attacker can use a carriage return character to end the header and inject malicious content, such as additional headers or an entirely new response body. This vulnerability is known as HTTP Response Splitting. While not an attack in itself, response splitting is a vector for several other attacks, such as cross-site scripting (XSS). This is related to CVE-2020-5247, which fixed this vulnerability but only for regular responses. This has been fixed in 4.3.3 and 3.12.4.
