| CVE-2022-45061 | 4 Fedoraproject, Netapp, Python and 1 more | 13 Fedora, Active Iq Unified Manager, Bootstrap Os and 10 more | 2024-11-21 | 7.5 High |
| An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname. For example, the attack payload could be placed in the Location header of an HTTP response with status code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16. | ||||
| CVE-2022-40188 | 3 Debian, Fedoraproject, Nic | 3 Debian Linux, Fedora, Knot Resolver | 2024-11-21 | 7.5 High |
| Knot Resolver before 5.5.3 allows remote attackers to cause a denial of service (CPU consumption) because of algorithmic complexity. During an attack, an authoritative server must return large NS sets or address sets. | ||||
| CVE-2022-39209 | 2 Fedoraproject, Github | 2 Fedora, Cmark-gfm | 2024-11-21 | 7.5 High |
| cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and rendering library and program in C. In versions prior to 0.29.0.gfm.6 a polynomial time complexity issue in cmark-gfm's autolink extension may lead to unbounded resource exhaustion and subsequent denial of service. Users may verify the patch by running `python3 -c 'print("![l"* 100000 + "\n")' | ./cmark-gfm -e autolink`, which will resource exhaust on unpatched cmark-gfm but render correctly on patched cmark-gfm. This vulnerability has been patched in 0.29.0.gfm.6. Users are advised to upgrade. Users unable to upgrade should disable the use of the autolink extension. | ||||
| CVE-2022-36021 | 1 Redis | 1 Redis | 2024-11-21 | 5.5 Medium |
| Redis is an in-memory database that persists on disk. Authenticated users can use string matching commands (like `SCAN` or `KEYS`) with a specially crafted pattern to trigger a denial-of-service attack on Redis, causing it to hang and consume 100% CPU time. The problem is fixed in Redis versions 6.0.18, 6.2.11, 7.0.9. | ||||
| CVE-2022-32149 | 2 Golang, Redhat | 10 Text, Acm, Container Native Virtualization and 7 more | 2024-11-21 | 7.5 High |
| An attacker may cause a denial of service by crafting an Accept-Language header which ParseAcceptLanguage will take significant time to parse. | ||||
| CVE-2022-22153 | 1 Juniper | 45 Junos, Mx10, Mx10000 and 42 more | 2024-11-21 | 7.5 High |
| An Insufficient Algorithmic Complexity combined with an Allocation of Resources Without Limits or Throttling vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX Series and MX Series with SPC3 allows an unauthenticated network attacker to cause latency in transit packet processing and even packet loss. If transit traffic includes a significant percentage (> 5%) of fragmented packets which need to be reassembled, high latency or packet drops might be observed. This issue affects Juniper Networks Junos OS on SRX Series, MX Series with SPC3: All versions prior to 18.2R3; 18.3 versions prior to 18.3R3; 18.4 versions prior to 18.4R2-S9, 18.4R3; 19.1 versions prior to 19.1R2; 19.2 versions prior to 19.2R1-S1, 19.2R2. | ||||
| CVE-2021-41168 | 1 Reddit | 1 Snudown | 2024-11-21 | 6.5 Medium |
| Snudown is a reddit-specific fork of the Sundown Markdown parser used by GitHub, with Python integration added. In affected versions snudown was found to be vulnerable to denial of service attacks to its reference table implementation. References written in markdown ` [reference_name]: https://www.example.com` are inserted into a hash table which was found to have a weak hash function, meaning that an attacker can reliably generate a large number of collisions for it. This makes the hash table vulnerable to a hash-collision DoS attack, a type of algorithmic complexity attack. Further the hash table allowed for duplicate entries resulting in long retrieval times. Proofs of concept and further discussion of the hash collision issue are discussed on the snudown GHSA(https://github.com/reddit/snudown/security/advisories/GHSA-6gvv-9q92-w5f6). Users are advised to update to version 1.7.0. | ||||
| CVE-2021-33582 | 4 Cyrus, Debian, Fedoraproject and 1 more | 5 Imap, Debian Linux, Fedora and 2 more | 2024-11-21 | 7.5 High |
| Cyrus IMAP before 3.4.2 allows remote attackers to cause a denial of service (multiple-minute daemon hang) via input that is mishandled during hash-table interaction. Because there are many insertions into a single bucket, strcmp becomes slow. This is fixed in 3.4.2, 3.2.8, and 3.0.16. | ||||
| CVE-2020-27223 | 6 Apache, Debian, Eclipse and 3 more | 22 Nifi, Solr, Spark and 19 more | 2024-11-21 | 5.3 Medium |
| In Eclipse Jetty 9.4.6.v20170531 to 9.4.36.v20210114 (inclusive), 10.0.0, and 11.0.0 when Jetty handles a request containing multiple Accept headers with a large number of “quality” (i.e. q) parameters, the server may enter a denial of service (DoS) state due to high CPU usage processing those quality values, resulting in minutes of CPU time exhausted processing those quality values. | ||||
| CVE-2020-14326 | 2 Netapp, Redhat | 7 Oncommand Insight, Camel Quarkus, Integration and 4 more | 2024-11-21 | 7.5 High |
| A vulnerability was found in RESTEasy, where RootNode incorrectly caches routes. This issue results in hash flooding, leading to slower requests with higher CPU time spent searching and adding the entry. This flaw allows an attacker to cause a denial of service. | ||||
| CVE-2019-19331 | 2 Debian, Nic | 2 Debian Linux, Knot Resolver | 2024-11-21 | 7.5 High |
| knot-resolver before version 4.3.0 is vulnerable to denial of service through high CPU utilization. DNS replies with very many resource records might be processed very inefficiently, in extreme cases taking even several CPU seconds for each such uncached message. For example, a few thousand A records can be squashed into one DNS message (limit is 64kB). | ||||
| CVE-2018-12558 | 1 Email\ | 1 \ | 2024-11-21 | N/A |
| The parse() method in the Email::Address module through 1.909 for Perl is vulnerable to Algorithmic complexity on specially prepared input, leading to Denial of Service. Prepared special input that caused this problem contained 30 form-field characters ("\f"). | ||||
| CVE-2017-11343 | 1 Call-cc | 1 Chicken | 2024-11-21 | N/A |
| Due to an incomplete fix for CVE-2012-6125, all versions of CHICKEN Scheme up to and including 4.12.0 are vulnerable to an algorithmic complexity attack. An attacker can provide crafted input which, when inserted into the symbol table, will result in O(n) lookup time. | ||||
| CVE-2016-10396 | 1 Ipsec-tools | 1 Ipsec-tools | 2024-11-21 | N/A |
| The racoon daemon in IPsec-Tools 0.8.2 contains a remotely exploitable computational-complexity attack when parsing and storing ISAKMP fragments. The implementation permits a remote attacker to exhaust computational resources on the remote endpoint by repeatedly sending ISAKMP fragment packets in a particular order such that the worst-case computational complexity is realized in the algorithm utilized to determine if reassembly of the fragments can take place. | ||||
| CVE-2015-8391 | 5 Fedoraproject, Oracle, Pcre and 2 more | 12 Fedora, Linux, Pcre and 9 more | 2024-11-21 | 9.8 Critical |
| The pcre_compile function in pcre_compile.c in PCRE before 8.38 mishandles certain [: nesting, which allows remote attackers to cause a denial of service (CPU consumption) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror. | ||||
| CVE-2015-7686 | 1 Email-address Project | 1 Email-address | 2024-11-21 | N/A |
| Algorithmic complexity vulnerability in Address.pm in the Email-Address module 1.908 and earlier for Perl allows remote attackers to cause a denial of service (CPU consumption) via a crafted string containing a list of e-mail addresses in conjunction with parenthesis characters that can be associated with nested comments. NOTE: the default configuration in 1.908 mitigates this vulnerability but misparses certain realistic comments. | ||||
| CVE-2015-4803 | 2 Oracle, Redhat | 7 Jdk, Jre, Jrockit and 4 more | 2024-11-21 | N/A |
| Unspecified vulnerability in Oracle Java SE 6u101, 7u85, and 8u60; Java SE Embedded 8u51; and JRockit R28.3.7 allows remote attackers to affect availability via vectors related to JAXP, a different vulnerability than CVE-2015-4893 and CVE-2015-4911. | ||||
| CVE-2015-4024 | 5 Apple, Hp, Oracle and 2 more | 13 Mac Os X, System Management Homepage, Linux and 10 more | 2024-11-21 | N/A |
