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the local file timestamp accidentally changed to a date newer than the one on the repository server, RMT would have an outdated file, which caused some errors.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 repos` caused 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 repositories` now works for custom     repositories.

  - Custom repository IDs can be the same across RMT     instances.

  - No more confusing 'SCC ID' vs 'ID' in `rmt-cli` output.
    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.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update for rmt-server fixes the following issues :

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.

Version 2.6.4

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.

Version 2.6.3

Instead of using an MD5 of URLs for custom repository friendly_ids, RMT now builds an ID from the name.

Version 2.6.2

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.

Version 2.6.1

Fixed an issue where relative paths supplied to `rmt-cli import repos` caused the command to fail.

Version 2.6.0

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 repositories` now works for custom     repositories.

  - Custom repository IDs can be the same across RMT     instances.

Version 2.5.20

Updated rails from 6.0.3.2 to 6.0.3.3 :

  - actionview (CVE-2020-15169)

Version 2.5.19

RMT now has the ability to remove local systems with the command `rmt-cli systems remove`.

Version 2.5.18

Fixed exit code for `rmt-cli mirror` and its subcommands. Now it exits with 1 whenever an error occurs during mirroring

Improved message logging for `rtm-cli mirror`. Instead of logging an error when it occurs, the command summarize all errors at the end of execution. Now log messages have colors to better identify failure/success.

Version 2.5.17

RMT no longer provides the installer updates repository to systems via its zypper service. This repository is used during the installation process, as it provides an up-to-date installation experience, but it has no use on an already installed system.

Version 2.5.16

Updated RMT's rails and puma dependencies.

  - puma (CVE-2020-11076, CVE-2020-11077, CVE-2020-5249,     CVE-2020-5247 CVE-2019-16770)

  - actionpack (CVE-2020-8185, CVE-2020-8164, CVE-2020-8166)

  - actionview (CVE-2020-8167, CVE-2020-5267, CVE-2019-5418,     CVE-2019-5419)

  - activesupport (CVE-2020-8165)

  - railties (CVE-2019-5420)

Version 2.5.15

RMT now checks if repositories are fully mirrored during the activation process. Previously, RMT only checked if the repositories were enabled to be mirrored, but not that they were actually mirrored.
In this case, RMTs were not able to provide the repository data which systems assumed it had.

Version 2.5.14

Enable 'Installer-Updates' repositories by default

Fixed deprecation warning when thor encountered an error. Also, instead of returning 0 for thor errors, rmt-cli will return 1 instead.

Version 2.5.13

Added `rmt-cli repos clean` command to remove locally mirrored files of repositories which are not marked to be mirrored.

Previously, RMT didn't track deduplicated files in its database. Now, to accommodate `rmt-cli repos clean`, RMT will track all mirrored files.

Move the nginx reload to the configuration package which contain nginx config files, don't reload nginx unconditionally from main package.

Version 2.5.12

Update rack to version 2.2.3 (CVE-2020-8184: bsc#1173351)

Update Rails to version 5.2.4.3 :

  - actionpack (CVE-2020-8164: bsc#1172177)

  - actionpack (CVE-2020-8166: bsc#1172182)

  - activesupport (CVE-2020-8165: bsc#1172186)

  - actionview (CVE-2020-8167: bsc#1172184)

Version 2.5.11

rmt-server-pubcloud :

  - SLES11 EOL

  - Extension activation verification based on the available     subscriptions

  - Added a manual instance verification script

Version 2.5.10

Support rmt-server to run with Ruby 2.7 (Factory/Tumbleweed) :

  - Bump gem 'config' version from 1.7.2 to 2.2.1 to fix     incompatibility Ruby 2.7 OpenStruct class;

  - Bump gem 'typhoeus' version from 1.3.1 to 1.4.0 in order     to also bump gem 'ethon' version, which caused a     'rb_safe_level' warning on Ruby 2.7;

  - Fix 'last arg as keyword arg' Ruby 2.7 warning on source     code;

  - Disable 'deprecated' warnings from Ruby 2.7; Rails 5.1     generates a lot of warnings with Ruby 2.7, mainly due to     'capturing the given block with Proc.new', which is     deprecated;

  - Improve RPM spec to consider only the distribution     default Ruby version configured in OBS;

  - Improve RPM spec to remove Ruby 2.7 warnings regarding     'bundler.

Move nginx/vhosts.d directory to correct sub-package. They are needed together with nginx, not rmt-server.

Fix dependencies especially for containerized usage :

  - mariadb and nginx are not hard requires, could run on     another host

Fix generic dependencies :

  - systemd ordering was missing

  - shadow is required for pre-install

Version 2.5.9

rmt-server-pubcloud: enforce strict authentication

Version 2.5.8

Use repomd_parser gem to remove repository metadata parsing code.

  - CVE-2020-8164: Possible Strong Parameters Bypass in     ActionPack. There is a strong parameters bypass vector     in ActionPack. (bsc#1172177)

This update was imported from the SUSE:SLE-15:Update update project.

Multiple security issues were discovered in the Rails web framework which could result in cross-site scripting, information leaks, code execution, cross-site request forgery or bypass of upload limits.

Multiple vulnerabilities were found in Ruby on Rails, a MVC ruby-based framework geared for web application development, which could lead to remote code execution and untrusted user input usage, depending on the application.

CVE-2020-8163

A code injection vulnerability in Rails would allow an attacker who controlled the `locals` argument of a `render` call to perform a RCE.

CVE-2020-8164

A deserialization of untrusted data vulnerability exists in rails which can allow an attacker to supply information can be inadvertently leaked from Strong Parameters.

CVE-2020-8165

A deserialization of untrusted data vulnernerability exists in rails that can allow an attacker to unmarshal user-provided objects in MemCacheStore and RedisCacheStore potentially resulting in an RCE.

Two vulnerabilities were found in Ruby on Rails, a MVC ruby-based framework geared for web application development, which could lead to remote code execution and untrusted user input usage, depending on the application.

CVE-2020-8164

Strong parameters bypass vector in ActionPack. In some cases user supplied information can be inadvertently leaked from Strong Parameters. Specifically the return value of `each`, or `each_value`, or `each_pair` will return the underlying 'untrusted' hash of data that was read from the parameters. Applications that use this return value may be inadvertently use untrusted user input.

CVE-2020-8165

Potentially unintended unmarshalling of user-provided objects in MemCacheStore. There is potentially unexpected behaviour in the MemCacheStore where, when untrusted user input is written to the cache store using the `raw: true` parameter, re-reading the result from the cache can evaluate the user input as a Marshalled object instead of plain text. Unmarshalling of untrusted user input can have impact up to and including RCE. At a minimum, this vulnerability allows an attacker to inject untrusted Ruby objects into a web application.

In addition to upgrading to the latest versions of Rails, developers should ensure that whenever they are calling `Rails.cache.fetch` they are using consistent values of the `raw` parameter for both reading and writing.

For Debian 8 'Jessie', these problems have been fixed in version 2:4.1.8-1+deb8u7.

We recommend that you upgrade your rails packages.
