CVE-2025-67726 2025-12-12 N/A 7.5 HIGH
Tornado is a Python web framework and asynchronous networking library. Versions 6.5.2 and below use an inefficient algorithm when parsing parameters for HTTP header values, potentially causing a DoS. The _parseparam function in httputil.py is used to parse specific HTTP header values, such as those in multipart/form-data and repeatedly calls string.count() within a nested loop while processing quoted semicolons. If an attacker sends a request with a large number of maliciously crafted parameters in a Content-Disposition header, the server's CPU usage increases quadratically (O(n²)) during parsing. Due to Tornado's single event loop architecture, a single malicious request can cause the entire server to become unresponsive for an extended period. This issue is fixed in version 6.5.3.
CVE-2025-55181 2025-12-04 N/A 5.3 MEDIUM
Sending an HTTP request/response body with greater than 2^31 bytes triggers an infinite loop in proxygen::coro::HTTPQuicCoroSession which blocks the backing event loop and unconditionally appends data to a std::vector per-loop iteration. This issue leads to unbounded memory growth and eventually causes the process to run out of memory.
CVE-2024-42237 1 Linux 1 Linux Kernel 2025-11-03 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: firmware: cs_dsp: Validate payload length before processing block Move the payload length check in cs_dsp_load() and cs_dsp_coeff_load() to be done before the block is processed. The check that the length of a block payload does not exceed the number of remaining bytes in the firwmware file buffer was being done near the end of the loop iteration. However, some code before that check used the length field without validating it.
CVE-2023-1993 3 Debian, Fedoraproject, Wireshark 3 Debian Linux, Fedora, Wireshark 2025-11-03 N/A 6.3 MEDIUM
LISP dissector large loop in Wireshark 4.0.0 to 4.0.4 and 3.6.0 to 3.6.12 allows denial of service via packet injection or crafted capture file

Large loops in multiple protocol dissectors in Wireshark 3.6.0 to 3.6.1 and 3.4.0 to 3.4.11 allow denial of service via packet injection or crafted capture file
CVE-2021-4190 2 Fedoraproject, Wireshark 2 Fedora, Wireshark 2025-11-03 5.0 MEDIUM 7.5 HIGH
Large loop in the Kafka dissector in Wireshark 3.6.0 allows denial of service via packet injection or crafted capture file
CVE-2025-62707 1 Pypdf Project 1 Pypdf 2025-10-27 N/A 7.5 HIGH
pypdf is a free and open-source pure-python PDF library. Prior to version 6.1.3, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires parsing the content stream of a page which has an inline image using the DCTDecode filter. This has been fixed in pypdf version 6.1.3.
CVE-2025-56571 1 Ebradyjobory 1 Finance.js 2025-10-08 N/A 7.5 HIGH
Finance.js v4.1.0 contains a Denial of Service (DoS) vulnerability via the IRR function’s depth parameter. Improper handling of the recursion/iteration limit can lead to excessive CPU usage, causing application stalls or crashes.
CVE-2025-6714 1 Mongodb 1 Mongodb 2025-10-03 N/A 7.5 HIGH
MongoDB Server's mongos component can become unresponsive to new connections due to incorrect handling of incomplete data. This affects MongoDB when configured with load balancer support. This issue affects MongoDB Server v6.0 prior to 6.0.23, MongoDB Server v7.0 prior to 7.0.20 and MongoDB Server v8.0 prior to 8.0.9 Required Configuration: This affects MongoDB sharded clusters when configured with load balancer support for mongos using HAProxy on specified ports.
CVE-2023-5632 1 Eclipse 1 Mosquitto 2025-06-25 N/A 7.5 HIGH
In Eclipse Mosquito before and including 2.0.5, establishing a connection to the mosquitto server without sending data causes the EPOLLOUT event to be added, which results excessive CPU consumption. This could be used by a malicious actor to perform denial of service type attack. This issue is fixed in 2.0.6
CVE-2024-25144 1 Liferay 3 Digital Experience Platform, Dxp, Liferay Portal 2025-05-13 N/A 4.1 MEDIUM
The IFrame widget in Liferay Portal 7.2.0 through 7.4.3.26, and older unsupported versions, and Liferay DXP 7.4 before update 27, 7.3 before update 6, 7.2 before fix pack 19, and older unsupported versions does not check the URL of the IFrame, which allows remote authenticated users to cause a denial-of-service (DoS) via a self referencing IFrame.
CVE-2023-3817 1 Openssl 1 Openssl 2025-05-05 N/A 5.3 MEDIUM
Issue summary: Checking excessively long DH keys or parameters may be very slow. Impact summary: Applications that use the functions DH_check(), DH_check_ex() or EVP_PKEY_param_check() to check a DH key or DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service. The function DH_check() performs various checks on DH parameters. After fixing CVE-2023-3446 it was discovered that a large q parameter value can also trigger an overly long computation during some of these checks. A correct q value, if present, cannot be larger than the modulus p parameter, thus it is unnecessary to perform these checks if q is larger than p. An application that calls DH_check() and supplies a key or parameters obtained from an untrusted source could be vulnerable to a Denial of Service attack. The function DH_check() is itself called by a number of other OpenSSL functions. An application calling any of those other functions may similarly be affected. The other functions affected by this are DH_check_ex() and EVP_PKEY_param_check(). Also vulnerable are the OpenSSL dhparam and pkeyparam command line applications when using the "-check" option. The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.
CVE-2017-13776 2 Debian, Graphicsmagick 2 Debian Linux, Graphicsmagick 2025-04-20 7.1 HIGH 6.5 MEDIUM
GraphicsMagick 1.3.26 has a denial of service issue in ReadXBMImage() in a coders/xbm.c "Read hex image data" version!=10 case that results in the reader not returning; it would cause large amounts of CPU and memory consumption although the crafted file itself does not request it.
CVE-2017-2330 1 Juniper 1 Northstar Controller 2025-04-20 4.9 MEDIUM 6.2 MEDIUM
A denial of service vulnerability in Juniper Networks NorthStar Controller Application prior to version 2.1.0 Service Pack 1 may allow an unauthenticated, local user, to create a fork bomb scenario, also known as a rabbit virus, or wabbit, which will create processes that replicate themselves, until all resources are consumed on the system, leading to a denial of service to the entire system until it is restarted. Continued attacks by an unauthenticated, local user, can lead to persistent denials of services.
CVE-2017-14175 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2025-04-20 7.1 HIGH 6.5 MEDIUM
In coders/xbm.c in ImageMagick 7.0.6-1 Q16, a DoS in ReadXBMImage() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted XBM file, which claims large rows and columns fields in the header but does not contain sufficient backing data, is provided, the loop over the rows would consume huge CPU resources, since there is no EOF check inside the loop.
CVE-2017-11549 1 Timidity\+\+ Project 1 Timidity\+\+ 2025-04-20 7.1 HIGH 5.5 MEDIUM
The play_midi function in playmidi.c in TiMidity++ 2.14.0 allows remote attackers to cause a denial of service (large loop and CPU consumption) via a crafted mid file. NOTE: CPU consumption might be relevant when using the --background option.
CVE-2017-14222 1 Ffmpeg 1 Ffmpeg 2025-04-20 7.1 HIGH 6.5 MEDIUM
In libavformat/mov.c in FFmpeg 3.3.3, a DoS in read_tfra() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption. When a crafted MOV file, which claims a large "item_count" field in the header but does not contain sufficient backing data, is provided, the loop would consume huge CPU and memory resources, since there is no EOF check inside the loop.
CVE-2017-0775 1 Google 1 Android 2025-04-20 7.1 HIGH 5.5 MEDIUM
A denial of service vulnerability in the Android media framework (libstagefright). Product: Android. Versions: 4.4.4, 5.0.2, 5.1.1, 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2, 8.0. Android ID: A-62673179.
CVE-2017-14171 1 Ffmpeg 1 Ffmpeg 2025-04-20 7.1 HIGH 6.5 MEDIUM
In libavformat/nsvdec.c in FFmpeg 2.4 and 3.3.3, a DoS in nsv_parse_NSVf_header() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted NSV file, which claims a large "table_entries_used" field in the header but does not contain sufficient backing data, is provided, the loop over 'table_entries_used' would consume huge CPU resources, since there is no EOF check inside the loop.
