"description": "The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:2588 advisory.\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. (CVE-2019-3881)\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. 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 - 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 - 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.

If Bundler is used in a\n scenario where the user does not have a writable home directory, an attacker could place malicious code in\n this directory that would be later loaded and executed. (CVE-2019-3881)\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. Specifically, use of JSON parsing methods can lead\n to creation of a malicious object within the interpreter, with adverse effects that are application-\n dependent. (CVE-2020-10663)\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\n BasicSocket#read_nonblock(requested_size, buffer, exception: false), the method resizes the buffer to fit\n the requested size, but no data is copied. Thus, the buffer string provides the previous value of the\n heap. This may expose possibly sensitive data from the interpreter. (CVE-2020-10933)\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\n simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An\n attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header\n check), which may lead to an HTTP Request Smuggling attack. (CVE-2020-25613)\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\n properly address XML round-trip issues.

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 - 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. (CVE-2019-3881)\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 - 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 - 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 - 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.

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.

Invalid reg-&gt; dmax processing in forward_search_range () can result in invalid pointer dereferencing, usually as an immediate denial-of-service condition. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2018-16468\nCVE-Crit: MEDIUM\nCVE-DESC: In the Loofah gem for Ruby, up to v2.2.2, raw JavaScript code may appear in the cleaned output when republishing a created SVG element. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2018-3740\nCVE-Crit: HIGH\nCVE-DESC: A specially crafted HTML snippet can cause the Sanitize gem for Ruby to allow non-whitelisted attributes in a whitelisted HTML element. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2018-3777\nCVE-Crit: CRITICAL\nCVE-DESC: Insufficient URI encoding in restforce before version 3.0.0 allows an attacker to inject arbitrary parameters into Salesforce API requests. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2018-8048\nCVE-Crit: MEDIUM\nCVE-DESC: In the Loofah gem prior to version 2.2.0 for Ruby, HTML attributes that are not whitelisted can appear in cleaned output by republishing the created HTML snippet. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2019-12732\nCVE-Crit: MEDIUM\nCVE-DESC: Chartkick gem up to version 3.1.0 for Ruby supports XSS. \nCVE-STATUS: Default\nCVE-REV: default\n \n \nCVE-ID: CVE-2019-17383\nCVE-Crit: CRITICAL\nCVE-DESC: netaddr gem before 2.0.4 for Ruby has incorrectly configured file permissions, so installing the gem may result in 0777 permissions on the target file system. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2019-16254\nCVE-Crit: MEDIUM\nCVE-DESC: Ruby up to versions 2.4.7, 2.5.x to 2.5.6, and 2.6.x to 2.6.4 allows HTTP response splitting. If a program using WEBrick inserts untrusted input into the response header, an attacker could use it to insert a newline character to split the header and inject malicious content to trick clients. NOTE: this issue exists due to an incomplete fix for CVE-2017-17742 that addressed the CRLF vector but did not address the isolated CR or isolated LF. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2019-15587\nCVE-Crit: MEDIUM\nCVE-DESC: In the Loofah gem for Ruby before v2.3.0, raw JavaScript may appear in the cleaned output when republishing a created SVG element. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2019-3881\nCVE-Crit: HIGH\nCVE-DESC: Bundler before 2.1.0 uses a predictable path in / tmp /, created with unprotected permissions, as the storage location for gems if locations in the user's home directory are unavailable. If Bundler is used in a scenario where the user does not have a writable home directory, an attacker could place malicious code in that directory that is later downloaded and executed. \nCVE-STATUS: Default\nCVE-REV: Default\n \n \nCVE-ID: CVE-2020-15237\nCVE-Crit: MEDIUM\nCVE-DESC: In Shrine before version 3.3.0, when using the `Derivation_endpoint` plug-in, an attacker could use a timing attack to guess the signature of a derived URL. The problem was fixed by comparing the sent and computed signature over a constant time using `Rack :: Utils.secure_compare`. Users using the `Derivation_endpoint` plugin are strongly recommended to upgrade to Shrine 3.3.0 or higher. A possible workaround is listed in the linked recommendations. \nCVE-STATUS: default\nCVE-REV: default\n \n \nCVE-ID: CVE-2020-14001\nCVE-Crit: CRITICAL\nCVE-DESC: The kramdown gem prior to 2.3.0 for Ruby by default handles the template parameter within Kramdown documents, allowing unintended read access (e.g., template = \"/ etc / passwd\") or unintended execution of Ruby embedded code (e.g., a string that starts with template = \"string: //\n", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2021-07-02T18:06:34", "type": "rosalinux", "title": "Advisory ROSA-SA-2021-1966", "bulletinFamily": "unix", "cvss2": {"severity": "HIGH", "exploitabilityScore": 4.9, "obtainAllPrivilege": false, "userInteractionRequired": true, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "HIGH", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 7.6, "vectorString": "AV:N/AC:H/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2012-6684", "CVE-2013-1812", "CVE-2013-6459", "CVE-2015-2963", "CVE-2015-4410", "CVE-2015-4411", "CVE-2015-9096", "CVE-2015-9097", "CVE-2016-6582", "CVE-2017-1002201", "CVE-2017-17742", "CVE-2017-9224", "CVE-2017-9225", "CVE-2017-9226", "CVE-2017-9227", "CVE-2017-9228", "CVE-2017-9229", "CVE-2018-16468", "CVE-2018-3740", "CVE-2018-3777", "CVE-2018-8048", "CVE-2019-12732", "CVE-2019-15587", "CVE-2019-16254", "CVE-2019-17383", "CVE-2019-3881", "CVE-2020-14001", "CVE-2020-15169", "CVE-2020-15237", "CVE-2020-16253", "CVE-2020-16254", "CVE-2020-25613", "CVE-2020-25739", "CVE-2020-26298", "CVE-2020-36190", "CVE-2020-5216", "CVE-2020-5217", "CVE-2020-5247", "CVE-2020-5249", "CVE-2020-7670", "CVE-2021-21289", "CVE-2021-28834", "CVE-2021-28965", "CVE-2021-29509"], "modified": "2021-07-02T18:06:34", "id": "ROSA-SA-2021-1966", "href": "https://abf.rosalinux.ru/advisories/ROSA-SA-2021-1966", "cvss": {"score": 7.6, "vector": "AV:N/AC:H/Au:N/C:C/I:C/A:C"}}]}
