| CVE-2022-23517 | 3 Debian, Redhat, Rubyonrails | 3 Debian Linux, Satellite, Rails Html Sanitizers | 2025-11-03 | 7.5 High |
| rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Certain configurations of rails-html-sanitizer < 1.4.4 use an inefficient regular expression that is susceptible to excessive backtracking when attempting to sanitize certain SVG attributes. This may lead to a denial of service through CPU resource consumption. This issue has been patched in version 1.4.4. | ||||
| CVE-2022-23516 | 2 Loofah Project, Redhat | 2 Loofah, Satellite | 2025-11-03 | 7.5 High |
| Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. Loofah >= 2.2.0, < 2.19.1 uses recursion for sanitizing CDATA sections, making it susceptible to stack exhaustion and raising a SystemStackError exception. This may lead to a denial of service through CPU resource consumption. This issue is patched in version 2.19.1. Users who are unable to upgrade may be able to mitigate this vulnerability by limiting the length of the strings that are sanitized. | ||||
| CVE-2022-23515 | 3 Debian, Loofah Project, Redhat | 3 Debian Linux, Loofah, Satellite | 2025-11-03 | 6.1 Medium |
| Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. Loofah >= 2.1.0, < 2.19.1 is vulnerable to cross-site scripting via the image/svg+xml media type in data URIs. This issue is patched in version 2.19.1. | ||||
| CVE-2022-23514 | 2 Loofah Project, Redhat | 2 Loofah, Satellite | 2025-11-03 | 7.5 High |
| Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. Loofah < 2.19.1 contains an inefficient regular expression that is susceptible to excessive backtracking when attempting to sanitize certain SVG attributes. This may lead to a denial of service through CPU resource consumption. This issue is patched in version 2.19.1. | ||||
| CVE-2022-0934 | 2 Redhat, Thekelleys | 3 Enterprise Linux, Rhel Eus, Dnsmasq | 2025-11-03 | 7.5 High |
| A single-byte, non-arbitrary write/use-after-free flaw was found in dnsmasq. This flaw allows an attacker who sends a crafted packet processed by dnsmasq, potentially causing a denial of service. | ||||
| CVE-2021-43859 | 6 Debian, Fedoraproject, Jenkins and 3 more | 14 Debian Linux, Fedora, Jenkins and 11 more | 2025-11-03 | 7.5 High |
| XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible. | ||||
| CVE-2021-42781 | 3 Fedoraproject, Opensc Project, Redhat | 3 Fedora, Opensc, Enterprise Linux | 2025-11-03 | 5.3 Medium |
| Heap buffer overflow issues were found in Opensc before version 0.22.0 in pkcs15-oberthur.c that could potentially crash programs using the library. | ||||
| CVE-2021-42780 | 3 Fedoraproject, Opensc Project, Redhat | 3 Fedora, Opensc, Enterprise Linux | 2025-11-03 | 5.3 Medium |
| A use after return issue was found in Opensc before version 0.22.0 in insert_pin function that could potentially crash programs using the library. | ||||
| CVE-2021-42779 | 3 Fedoraproject, Opensc Project, Redhat | 3 Fedora, Opensc, Enterprise Linux | 2025-11-03 | 5.3 Medium |
| A heap use after free issue was found in Opensc before version 0.22.0 in sc_file_valid. | ||||
| CVE-2021-42778 | 3 Fedoraproject, Opensc Project, Redhat | 3 Fedora, Opensc, Enterprise Linux | 2025-11-03 | 5.3 Medium |
| A heap double free issue was found in Opensc before version 0.22.0 in sc_pkcs15_free_tokeninfo. | ||||
| CVE-2021-3733 | 4 Fedoraproject, Netapp, Python and 1 more | 21 Extra Packages For Enterprise Linux, Fedora, Hci Compute Node Firmware and 18 more | 2025-11-03 | 6.5 Medium |
| There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability. | ||||
| CVE-2021-3669 | 5 Debian, Fedoraproject, Ibm and 2 more | 24 Debian Linux, Fedora, Spectrum Copy Data Management and 21 more | 2025-11-03 | 5.5 Medium |
| A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large shared memory segment counts which could lead to resource exhaustion and DoS. | ||||
| CVE-2021-3377 | 2 Ansi Up Project, Redhat | 2 Ansi Up, Acm | 2025-11-03 | 6.1 Medium |
| The npm package ansi_up converts ANSI escape codes into HTML. In ansi_up v4, ANSI escape codes can be used to create HTML hyperlinks. Due to insufficient URL sanitization, this feature is affected by a cross-site scripting (XSS) vulnerability. This issue is fixed in v5.0.0. | ||||
| CVE-2021-36087 | 3 Fedoraproject, Redhat, Selinux Project | 3 Fedora, Enterprise Linux, Selinux | 2025-11-03 | 3.3 Low |
| The CIL compiler in SELinux 3.2 has a heap-based buffer over-read in ebitmap_match_any (called indirectly from cil_check_neverallow). This occurs because there is sometimes a lack of checks for invalid statements in an optional block. | ||||
| CVE-2021-36086 | 3 Fedoraproject, Redhat, Selinux Project | 3 Fedora, Enterprise Linux, Selinux | 2025-11-03 | 3.3 Low |
| The CIL compiler in SELinux 3.2 has a use-after-free in cil_reset_classpermission (called from cil_reset_classperms_set and cil_reset_classperms_list). | ||||
| CVE-2021-36085 | 3 Fedoraproject, Redhat, Selinux Project | 3 Fedora, Enterprise Linux, Selinux | 2025-11-03 | 3.3 Low |
| The CIL compiler in SELinux 3.2 has a use-after-free in __cil_verify_classperms (called from __verify_map_perm_classperms and hashtab_map). | ||||
| CVE-2021-36084 | 3 Fedoraproject, Redhat, Selinux Project | 3 Fedora, Enterprise Linux, Selinux | 2025-11-03 | 3.3 Low |
| The CIL compiler in SELinux 3.2 has a use-after-free in __cil_verify_classperms (called from __cil_verify_classpermission and __cil_pre_verify_helper). | ||||
| CVE-2021-32839 | 2 Redhat, Sqlparse Project | 3 Satellite, Satellite Capsule, Sqlparse | 2025-11-03 | 7.5 High |
| sqlparse is a non-validating SQL parser module for Python. In sqlparse versions 0.4.0 and 0.4.1 there is a regular Expression Denial of Service in sqlparse vulnerability. The regular expression may cause exponential backtracking on strings containing many repetitions of '\r\n' in SQL comments. Only the formatting feature that removes comments from SQL statements is affected by this regular expression. As a workaround don't use the sqlformat.format function with keyword strip_comments=True or the --strip-comments command line flag when using the sqlformat command line tool. The issues has been fixed in sqlparse 0.4.2. | ||||
| CVE-2021-29921 | 3 Oracle, Python, Redhat | 8 Communications Cloud Native Core Automated Test Suite, Communications Cloud Native Core Binding Support Function, Communications Cloud Native Core Network Slice Selection Function and 5 more | 2025-11-03 | 9.8 Critical |
| In Python before 3,9,5, the ipaddress library mishandles leading zero characters in the octets of an IP address string. This (in some situations) allows attackers to bypass access control that is based on IP addresses. | ||||
| CVE-2021-23566 | 2 Nanoid Project, Redhat | 4 Nanoid, Acm, Openshift and 1 more | 2025-11-03 | 4 Medium |
| The package nanoid from 3.0.0 and before 3.1.31 are vulnerable to Information Exposure via the valueOf() function which allows to reproduce the last id generated. | ||||
