| CVE-2022-40188 | 3 Debian, Fedoraproject, Nic | 3 Debian Linux, Fedora, Knot Resolver | 2026-06-17 | N/A | 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 | 2026-06-17 | N/A | 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 | 2026-06-17 | N/A | 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-2022-22153 | 1 Juniper | 45 Junos, Mx10, Mx10000 and 42 more | 2026-06-17 | 5.0 MEDIUM | 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 | 2026-06-17 | 4.0 MEDIUM | 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 | 3 Cyrus, Debian, Fedoraproject | 3 Imap, Debian Linux, Fedora | 2026-06-17 | 5.0 MEDIUM | 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-2020-3548 | 1 Cisco | 1 Email Security Appliance | 2026-06-17 | N/A | 5.3 MEDIUM |
| A vulnerability in the Transport Layer Security (TLS) protocol implementation of Cisco AsyncOS software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to cause high CPU usage on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to inefficient processing of incoming TLS traffic. An attacker could exploit this vulnerability by sending a series of crafted TLS packets to an affected device. A successful exploit could allow the attacker to trigger a prolonged state of high CPU utilization. The affected device would still be operative, but response time and overall performance may be degraded.There are no workarounds that address this vulnerability. | |||||
| CVE-2020-27223 | 5 Apache, Debian, Eclipse and 2 more | 16 Nifi, Solr, Spark and 13 more | 2026-06-17 | 4.3 MEDIUM | 5.2 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-2019-19331 | 2 Debian, Nic | 2 Debian Linux, Knot Resolver | 2026-06-17 | 5.0 MEDIUM | 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 \ | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| 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 | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| 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 | 2026-06-17 | 7.8 HIGH | 7.5 HIGH |
| 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. | |||||
