CVE-2024-39702 1 Openresty 1 Openresty 2025-09-24 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 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-2020-27223 6 Apache, Debian, Eclipse and 3 more 22 Nifi, Solr, Spark and 19 more 2025-08-20 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-2024-9631 1 Gitlab 1 Gitlab 2025-08-06 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 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 2 Email Security Appliance, Secure Email 2025-07-31 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 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 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 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-2022-32149 2 Golang, Redhat 10 Text, Acm, Container Native Virtualization and 7 more 2025-05-15 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-2022-39209 2 Fedoraproject, Github 2 Fedora, Cmark-gfm 2025-04-23 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-2016-10396 1 Ipsec-tools 1 Ipsec-tools 2025-04-20 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-2012-0881 1 Apache 1 Xerces2 Java 2025-04-20 N/A
Apache Xerces2 Java Parser before 2.12.0 allows remote attackers to cause a denial of service (CPU consumption) via a crafted message to an XML service, which triggers hash table collisions.
CVE-2017-11343 1 Call-cc 1 Chicken 2025-04-20 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-2012-0880 1 Apache 1 Xerces-c\+\+ 2025-04-20 N/A
Apache Xerces-C++ allows remote attackers to cause a denial of service (CPU consumption) via a crafted message sent to an XML service that causes hash table collisions.
