This release includes security fixes. Please check the topics below for details.

CVE-2019-15845: A NUL injection vulnerability of File.fnmatch and File.fnmatch?

A NUL injection vulnerability of Ruby built-in methods (File.fnmatch and File.fnmatch?) was found. An attacker who has the control of the path pattern parameter could exploit this vulnerability to make path matching pass despite the intention of the program author.

CVE-2019-16201: Regular Expression Denial of Service vulnerability of WEBrick's Digest access authentication

Regular expression denial of service vulnerability of WEBrick's Digest authentication module was found. An attacker can exploit this vulnerability to cause an effective denial of service against a WEBrick service.

CVE-2019-16254: HTTP response splitting in WEBrick (Additional fix)

There is an HTTP response splitting vulnerability in WEBrick bundled with Ruby.

CVE-2019-16255: A code injection vulnerability of Shell#[] and Shell#test

A code injection vulnerability of Shell#[] and Shell#test in a standard library (lib/shell.rb) was found.

According to the versions of the ruby packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x     through 2.6.4 allows code injection if the first     argument (aka the 'command' argument) to Shell#[] or     Shell#test in lib/shell.rb is untrusted data. An     attacker can exploit this to call an arbitrary Ruby     method.(CVE-2019-16255)

  - Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x     through 2.6.4 allows HTTP Response Splitting. If a     program using WEBrick inserts untrusted input into the     response header, an attacker can exploit it to insert a     newline character to split a header, and inject     malicious content to deceive clients. NOTE: this issue     exists because of an incomplete fix for CVE-2017-17742,     which addressed the CRLF vector, but did not address an     isolated CR or an isolated LF.(CVE-2019-16254)

  - WEBrick::HTTPAuth::DigestAuth in Ruby through 2.4.7,     2.5.x through 2.5.6, and 2.6.x through 2.6.4 has a     regular expression Denial of Service cause by     looping/backtracking. A victim must expose a WEBrick     server that uses DigestAuth to the Internet or a     untrusted network.(CVE-2019-16201)

  - Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x     through 2.6.4 mishandles path checking within     File.fnmatch functions.(CVE-2019-15845)

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

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2021:2588 advisory.

    * rubygem-bundler: Insecure permissions on directory in /tmp/ allows for execution of malicious code     (CVE-2019-3881)

    * ruby: NUL injection vulnerability of File.fnmatch and File.fnmatch? (CVE-2019-15845)

    * ruby: Regular expression denial of service vulnerability of WEBrick's Digest authentication     (CVE-2019-16201)

    * ruby: Code injection via command argument of Shell#test / Shell#[] (CVE-2019-16255)

    * rubygem-json: Unsafe object creation vulnerability in JSON (CVE-2020-10663)

    * ruby: BasicSocket#read_nonblock method leads to information disclosure (CVE-2020-10933)

    * ruby: Potential HTTP request smuggling in WEBrick (CVE-2020-25613)

    * ruby: XML round-trip vulnerability in REXML (CVE-2021-28965)

    * ruby: HTTP response splitting in WEBrick (CVE-2019-16254)

Tenable has extracted the preceding description block directly from the AlmaLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
