**Issue Overview:**
The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through 2.6.5, has an Unsafe Object Creation Vulnerability. This is quite similar to CVE-2013-0269, but does not rely on poor garbage-collection behavior within Ruby. Specifically, use of JSON parsing methods can lead to creation of a malicious object within the interpreter, with adverse effects that are application-dependent. (CVE-2020-10663)
**Affected Packages:**
rubygem-json
**Issue Correction:**
Run _yum update rubygem-json_ to update your system.

NOTE: this issue\n exists because of an incomplete fix for CVE-2017-17742,\n which addressed the CRLF vector, but did not address an\n isolated CR or an isolated LF.(CVE-2019-16254)\n\n - Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x\n through 2.6.4 mishandles path checking within\n File.fnmatch functions.(CVE-2019-15845)\n\n - Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x\n through 2.6.4 allows code injection if the first\n argument (aka the 'command' argument) to Shell#[] or\n Shell#test in lib/shell.rb is untrusted data. An\n attacker can exploit this to call an arbitrary Ruby\n method.(CVE-2019-16255)\n\n - The JSON gem through 2.2.0 for Ruby, as used in Ruby\n 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through\n 2.6.5, has an Unsafe Object Creation Vulnerability.\n This is quite similar to CVE-2013-0269, but does not\n rely on poor garbage-collection behavior within Ruby.\n Specifically, use of JSON parsing methods can lead to\n creation of a malicious object within the interpreter,\n with adverse effects that are\n application-dependent.(CVE-2020-10663)\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the EulerOS security advisory.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1422 advisory.\n\n - jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The jQuery(strInput) function does not differentiate selectors from HTML in a reliable fashion. In vulnerable versions, jQuery determined whether the input was HTML by looking for the '<' character anywhere in the string, giving attackers more flexibility when attempting to construct a malicious payload. In fixed versions, jQuery only deems the input to be HTML if it explicitly starts with the '<' character, limiting exploitability only to attackers who can control the beginning of a string, which is far less common. (CVE-2012-6708)\n\n - The JSON gem before 1.5.5, 1.6.x before 1.6.8, and 1.7.x before 1.7.7 for Ruby allows remote attackers to cause a denial of service (resource consumption) or bypass the mass assignment protection mechanism via a crafted JSON document that triggers the creation of arbitrary Ruby symbols or certain internal objects, as demonstrated by conducting a SQL injection attack against Ruby on Rails, aka Unsafe Object Creation Vulnerability. (CVE-2013-0269)\n\n - jQuery before 3.0.0 is vulnerable to Cross-site Scripting (XSS) attacks when a cross-domain Ajax request is performed without the dataType option, causing text/javascript responses to be executed.\n (CVE-2015-9251)\n\n - Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1 allows an HTTP Response Splitting attack. An attacker can inject a crafted key and value into an HTTP response for the HTTP server of WEBrick. (CVE-2017-17742)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through 2.6.5, has an Unsafe Object Creation Vulnerability.

It is, therefore, affected by\nmultiple vulnerabilities as referenced in the ALAS-2020-1422 advisory.\n\n - jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The jQuery(strInput) function\n does not differentiate selectors from HTML in a reliable fashion. In vulnerable versions, jQuery\n determined whether the input was HTML by looking for the '<' character anywhere in the string, giving\n attackers more flexibility when attempting to construct a malicious payload. In fixed versions, jQuery\n only deems the input to be HTML if it explicitly starts with the '<' character, limiting exploitability\n only to attackers who can control the beginning of a string, which is far less common. (CVE-2012-6708)\n\n - The JSON gem before 1.5.5, 1.6.x before 1.6.8, and 1.7.x before 1.7.7 for Ruby allows remote attackers to\n cause a denial of service (resource consumption) or bypass the mass assignment protection mechanism via a\n crafted JSON document that triggers the creation of arbitrary Ruby symbols or certain internal objects, as\n demonstrated by conducting a SQL injection attack against Ruby on Rails, aka Unsafe Object Creation\n Vulnerability. (CVE-2013-0269)\n\n - jQuery before 3.0.0 is vulnerable to Cross-site Scripting (XSS) attacks when a cross-domain Ajax request\n is performed without the dataType option, causing text/javascript responses to be executed.\n (CVE-2015-9251)\n\n - Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1 allows\n an HTTP Response Splitting attack. An attacker can inject a crafted key and value into an HTTP response\n for the HTTP server of WEBrick. (CVE-2017-17742)\n\n - Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 mishandles path checking within\n File.fnmatch functions. (CVE-2019-15845)\n\n - 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\n regular expression Denial of Service cause by looping/backtracking. A victim must expose a WEBrick server\n that uses DigestAuth to the Internet or a untrusted network. (CVE-2019-16201)\n\n - 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\n program using WEBrick inserts untrusted input into the response header, an attacker can exploit it to\n insert a newline character to split a header, and inject malicious content to deceive clients. NOTE: this\n issue exists because of an incomplete fix for CVE-2017-17742, which addressed the CRLF vector, but did not\n address an isolated CR or an isolated LF. (CVE-2019-16254)\n\n - 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\n argument (aka the command argument) to Shell#[] or Shell#test in lib/shell.rb is untrusted data. An\n attacker can exploit this to call an arbitrary Ruby method. (CVE-2019-16255)\n\n - The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through\n 2.6.5, has an Unsafe Object Creation Vulnerability. This is quite similar to CVE-2013-0269, but does not\n rely on poor garbage-collection behavior within Ruby.

that are affected by multiple vulnerabilities as referenced in the ELSA-2021-2587 advisory.\n\n - The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through 2.6.5, has an Unsafe Object Creation Vulnerability. This is quite similar to CVE-2013-0269, but does not rely on poor garbage-collection behavior within Ruby. Specifically, use of JSON parsing methods can lead to creation of a malicious object within the interpreter, with adverse effects that are application- dependent. (CVE-2020-10663)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack. (CVE-2020-25613)\n\n - An issue was discovered in Ruby 2.5.x through 2.5.7, 2.6.x through 2.6.5, and 2.7.0. If a victim calls BasicSocket#read_nonblock(requested_size, buffer, exception: false), the method resizes the buffer to fit the requested size, but no data is copied. Thus, the buffer string provides the previous value of the heap. This may expose possibly sensitive data from the interpreter. (CVE-2020-10933)\n\n - The REXML gem before 3.2.5 in Ruby before 2.6.7, 2.7.x before 2.7.3, and 3.x before 3.0.1 does not properly address XML round-trip issues. An incorrect document can be produced after parsing and serializing.

"2023-05-20T14:57:15", "description": "The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2021-2588 advisory.\n\n - The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through 2.6.5, has an Unsafe Object Creation Vulnerability. This is quite similar to CVE-2013-0269, but does not rely on poor garbage-collection behavior within Ruby. Specifically, use of JSON parsing methods can lead to creation of a malicious object within the interpreter, with adverse effects that are application- dependent. (CVE-2020-10663)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - 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)\n\n - An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack. (CVE-2020-25613)\n\n - An issue was discovered in Ruby 2.5.x through 2.5.7, 2.6.x through 2.6.5, and 2.7.0. If a victim calls BasicSocket#read_nonblock(requested_size, buffer, exception: false), the method resizes the buffer to fit the requested size, but no data is copied. Thus, the buffer string provides the previous value of the heap. This may expose possibly sensitive data from the interpreter. (CVE-2020-10933)\n\n - The REXML gem before 3.2.5 in Ruby before 2.6.7, 2.7.x before 2.7.3, and 3.x before 3.0.1 does not properly address XML round-trip issues. An incorrect document can be produced after parsing and serializing. (CVE-2021-28965)\n\n - Bundler prior to 2.1.0 uses a predictable path in /tmp/, created with insecure permissions as a storage location for gems, if locations under the user's home directory are not available. If Bundler is used in a scenario where the user does not have a writable home directory, an attacker could place malicious code in this directory that would be later loaded and executed.

several security issues, multiple bugs, and adds various enhancements, is now available.\n\nThe Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.\n\nRed Hat Subscription Asset Manager acts as a proxy for handling subscription information and software updates on client machines.\n\nThe latest packages for Subscription Asset Manager include a number of security fixes :\n\nWhen a Subscription Asset Manager instance is created, its configuration script automatically creates an RPM of the internal subscription service CA certificate. However, this RPM incorrectly created the CA certificate with file permissions of 0666. This allowed other users on a client system to modify the CA certificate used to trust the remote subscription server. All administrators are advised to update and deploy the subscription service certificate on all systems which use Subscription Asset Manager as their subscription service. This procedure is described in:\nhttps://access.redhat.com/knowledge/docs/en-US/ Red_Hat_Subscription_Asset_Manager/1.2/html/Installation_Guide/ sect-Installation_Guide-Administration-Upgrading_Subscription_Asset_Ma nager.html (CVE-2012-6116)\n\nManifest signature checking was not implemented for early versions of Subscription Asset Manager. This meant that a malicious user could edit a manifest file, insert arbitrary data, and successfully upload the edited manifest file into the Subscription Asset Manager server.\n(CVE-2012-6119)\n\nRuby's documentation generator had a flaw in the way it generated HTML documentation. When a Ruby application exposed its documentation on a network (such as a web page), an attacker could use a specially- crafted URL to open an arbitrary web script or to execute HTML code within the application's user session. (CVE-2013-0256)\n\nA timing attack flaw was found in the way rubygem-rack and ruby193-rubygem-rack processed HMAC digests in cookies. This flaw could aid an attacker using forged digital signatures to bypass authentication checks. (CVE-2013-0263)\n\nA flaw in rubygem-json allowed remote attacks by creating different types of malicious objects. For example, it could initiate a denial of service (DoS) attack through resource consumption by using a JSON document to create arbitrary Ruby symbols, which were never garbage collected. It could also be exploited to create internal objects which could allow a SQL injection attack. (CVE-2013-0269)\n\nA flaw in ActiveRecord in Ruby on Rails allowed remote attackers to circumvent attribute protections and to insert their own crafted requests to change protected attribute values. (CVE-2013-0276)\n\nHTML markup was not properly escaped when filling in the username field in the Notifications form of the Subscription Asset Manager UI.\nThis meant that HTML code used in the value was then applied in the UI page when the entry was viewed. This could have allowed malicious HTML code to be entered. The field value is now validated and any HTML tags are escaped. (CVE-2013-1823)\n\nThese updated packages also include bug fixes and enhancements :\n\n* Previously, no SELinux policy for the subscription service was included with the Subscription Asset Manager packages. The candlepin-selinux package is now included with SELinux policies for the subscription server. (BZ#906901)\n\n* When attempting to use the subscription service's CA certificate to validate a manifest during import, the comparison failed. The upstream subscription service which generated the manifest is a different service than the local subscription service; thus, they have different CA certificates. This caused importing a manifest to fail with the error 'archive failed signature'. This has been fixed so that the proper certificate is used for verification.
