CVE-2024-39702 1 Openresty 1 Openresty 2025-09-24 N/A 5.9 MEDIUM
In lj_str_hash.c in OpenResty 1.19.3.1 through 1.25.3.1, the string hashing function (used during string interning) allows HashDoS (Hash Denial of Service) attacks. An attacker could cause excessive resource usage during proxy operations via crafted requests, potentially leading to a denial of service with relatively few incoming requests. This vulnerability only exists in the OpenResty fork in the openresty/luajit2 GitHub repository. The LuaJIT/LuaJIT repository. is unaffected.
CVE-2025-55304 1 Exiv2 1 Exiv2 2025-09-02 N/A 5.5 MEDIUM
Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. A denial-of-service was found in Exiv2 version 0.28.5: a quadratic algorithm in the ICC profile parsing code in jpegBase::readMetadata() can cause Exiv2 to run for a long time. The denial-of-service is triggered when Exiv2 is used to read the metadata of a crafted jpg image file. The bug is fixed in version 0.28.6.
CVE-2024-9631 1 Gitlab 1 Gitlab 2025-08-06 N/A 7.5 HIGH
An issue was discovered in GitLab CE/EE affecting all versions starting from 13.6 prior to 17.2.9, starting from 17.3 prior to 17.3.5, and starting from 17.4 prior to 17.4.2, where viewing diffs of MR with conflicts can be slow.
CVE-2024-6324 1 Gitlab 1 Gitlab 2025-08-05 N/A 4.3 MEDIUM
An issue was discovered in GitLab CE/EE affecting all versions starting from 15.7 prior to 17.5.5, starting from 17.6 prior to 17.6.3, and starting from 17.7 prior to 17.7.1. It was possible to trigger a DoS by creating cyclic references between epics.
CVE-2020-3548 1 Cisco 1 Email Security Appliance 2025-07-31 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-2024-8233 1 Gitlab 1 Gitlab 2025-07-11 N/A 7.5 HIGH
An issue has been discovered in GitLab CE/EE affecting all versions from 9.4 before 17.4.6, 17.5 before 17.5.4, and 17.6 before 17.6.2. An attacker could cause a denial of service with requests for diff files on a commit or merge request.
CVE-2023-38285 1 Owasp 1 Modsecurity 2025-07-03 N/A 7.5 HIGH
Trustwave ModSecurity 3.x before 3.0.10 has Inefficient Algorithmic Complexity.
CVE-2022-40188 3 Debian, Fedoraproject, Nic 3 Debian Linux, Fedora, Knot Resolver 2025-05-27 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-2017-11343 1 Call-cc 1 Chicken 2025-04-20 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 2025-04-20 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.
CVE-2023-2473 1 Iteachyou 1 Dreamer Cms 2025-04-04 4.0 MEDIUM 4.3 MEDIUM
A vulnerability was found in Dreamer CMS up to 4.1.3. It has been declared as problematic. This vulnerability affects the function updatePwd of the file UserController.java of the component Password Hash Calculation. The manipulation leads to inefficient algorithmic complexity. The attack can be initiated remotely. It is recommended to upgrade the affected component. The identifier of this vulnerability is VDB-227860.
CVE-2024-43484 3 Apple, Linux, Microsoft 21 Macos, Linux Kernel, .net and 18 more 2025-03-28 N/A 7.5 HIGH
.NET, .NET Framework, and Visual Studio Denial of Service Vulnerability
CVE-2025-30348 1 Qt 1 Qt 2025-03-24 N/A 5.8 MEDIUM
encodeText in QDom in Qt before 6.8.0 has a complex algorithm involving XML string copy and inline replacement of parts of a string (with relocation of later data).
CVE-2023-4408 3 Fedoraproject, Isc, Netapp 3 Fedora, Bind, Ontap 2025-03-14 N/A 7.5 HIGH
The DNS message parsing code in `named` includes a section whose computational complexity is overly high. It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive CPU load on the affected `named` instance by exploiting this flaw. This issue affects both authoritative servers and recursive resolvers. This issue affects BIND 9 versions 9.0.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1.

By leveraging this vulnerability an attacker could create a DoS condition by sending crafted API calls. This was a regression of an earlier patch.
CVE-2023-36810 1 Pypdf Project 1 Pypdf 2024-11-21 N/A 6.2 MEDIUM
pypdf is a pure-python PDF library capable of splitting, merging, cropping, and transforming the pages of PDF files. An attacker who uses this vulnerability can craft a PDF which leads to unexpected long runtime. This quadratic runtime blocks the current process and can utilize a single core of the CPU by 100%. It does not affect memory usage. This issue has been addressed in PR 808 and versions from 1.27.9 include this fix. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2023-26485 1 Github 1 Cmark-gfm 2024-11-21 N/A 5.3 MEDIUM
cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and rendering library and program in C. A polynomial time complexity issue in cmark-gfm may lead to unbounded resource exhaustion and subsequent denial of service. This CVE covers quadratic complexity issues when parsing text which leads with either large numbers of `_` characters. This issue has been addressed in version 0.29.0.gfm.10. Users are advised to upgrade. Users unable to upgrade should validate that their input comes from trusted sources. ### Impact A polynomial time complexity issue in cmark-gfm may lead to unbounded resource exhaustion and subsequent denial of service. ### Proof of concept ``` $ ~/cmark-gfm$ python3 -c 'pad = "_" * 100000; print(pad + "." + pad, end="")' | time ./build/src/cmark-gfm --to plaintext ``` Increasing the number 10000 in the above commands causes the running time to increase quadratically. ### Patches This vulnerability have been patched in 0.29.0.gfm.10. ### Note on cmark and cmark-gfm XXX: TBD [cmark-gfm](https://github.com/github/cmark-gfm) is a fork of [cmark](https://github.com/commonmark/cmark) that adds the GitHub Flavored Markdown extensions. The two codebases have diverged over time, but share a common core. These bugs affect both `cmark` and `cmark-gfm`. ### Credit We would like to thank @gravypod for reporting this vulnerability. ### References https://en.wikipedia.org/wiki/Time_complexity ### For more information If you have any questions or comments about this advisory: * Open an issue in [github/cmark-gfm](https://github.com/github/cmark-gfm)
