A remote attacker might be able to cause infinite recursion in PowerDNS Recursor 4.8.0 via a DNS query that retrieves DS records for a misconfigured domain, because QName minimization is used in QM fallback mode. This is fixed in 4.8.1.

In dotCMS 5.x-22.06, it is possible to call the TempResource multiple times, each time requesting the dotCMS server to download a large file. If done repeatedly, this will result in Tomcat request-thread exhaustion and ultimately a denial of any other requests.

In Moodle, the file repository's URL parsing required additional recursion handling to mitigate the risk of recursion denial of service.

Stack exhaustion in json-smart leads to denial of service when parsing malformed JSON

[Json-smart](https://netplex.github.io/json-smart/) is a performance focused, JSON processor lib. When reaching a ‘[‘ or ‘{‘ character in the JSON input, the code parses an array or an object respectively. It was discovered that the code does not have any limit to the nesting of such arrays or objects. Since the parsing of nested arrays and objects is done recursively, nesting too many of them can cause a stack exhaustion (stack overflow) and crash the software.

Infinite recursion in Jettison leads to denial of service when creating a crafted JSONArray

An infinite recursion is triggered in Jettison when constructing a JSONArray from a Collection that contains a self-reference in one of its elements. This leads to a StackOverflowError exception being thrown.

kernel: lib/nlattr.c allows attackers to cause a denial of service

An issue was discovered in the Linux kernel before 5.8. lib/nlattr.c allows attackers to cause a denial of service (unbounded recursion) via a nested Netlink policy with a back reference.

A denial of service vulnerability exists in the FitsOutput::close() functionality of OpenImageIO Project OpenImageIO v2.4.7.1. A specially crafted ImageOutput Object can lead to denial of service. An attacker can provide malicious input to trigger this vulnerability.

Telefnica Brasil Vivo Play (IPTV) Firmware: 2023.04.04.01.06.15 is vulnerable to Denial of Service (DoS) via DNS Recursion.

Stack overflow in Xpdf 4.05 due to object loop in PDF object stream

In Xpdf 4.05 (and earlier), a PDF object loop in an object stream leads to infinite recursion and a stack overflow.

Stack overflow in Xpdf 4.05 due to object loop in attachments

In Xpdf 4.05 (and earlier), a PDF object loop in the attachments leads to infinite recursion and a stack overflow.

Stack overflow in Xpdf 4.05 due to object loop in PDF resources

In Xpdf 4.05 (and earlier), a PDF object loop in the PDF resources leads to infinite recursion and a stack overflow.

Stack overflow in Xpdf 4.04 due to object loop in PDF page label tree

 In Xpdf 4.04 (and earlier), a PDF object loop in the page label tree leads to infinite recursion and a stack overflow.

Stack overflow in Xpdf 4.04 due to object loop in PDF embedded file tree

 In Xpdf 4.04 (and earlier), a PDF object loop in the embedded file tree leads to infinite recursion and a stack overflow.

Remarshal prior to v0.17.1 expands YAML alias nodes unlimitedly, hence Remarshal is vulnerable to Billion Laughs Attack. Processing untrusted YAML files may cause a denial-of-service (DoS) condition.

Fortra Globalscape Administration Server Denial of Service

Fortra Globalscape EFT versions before 8.1.0.16 suffer from a denial of service vulnerability, where a compressed message that decompresses to itself can cause infinite recursion and crash the service

python: RecursionError: maximum recursion depth exceeded while calling a Python object

The legacy email.utils.parseaddr function in Python through 3.11.4 allows attackers to trigger "RecursionError: maximum recursion depth exceeded while calling a Python object" via a crafted argument. This argument is plausibly an untrusted value from an application's input data that was supposed to contain a name and an e-mail address. NOTE: email.utils.parseaddr is categorized as a Legacy API in the documentation of the Python email package. Applications should instead use the email.parser.BytesParser or email.parser.Parser class. NOTE: the vendor's perspective is that this is neither a vulnerability nor a bug. The email package is intended to have size limits and to throw an exception when limits are exceeded; they were exceeded by the example demonstration code.

Denial of service due to unbounded recursion in QuickTimeVideo::multipleEntriesDecoder in Exiv2

Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A denial-of-service was found in Exiv2 version v0.28.1: an unbounded recursion can cause Exiv2 to crash by exhausting the stack. The vulnerable function, `QuickTimeVideo::multipleEntriesDecoder`, was new in v0.28.0, so Exiv2 versions before v0.28 are _not_ affected. The denial-of-service is triggered when Exiv2 is used to read the metadata of a crafted video file. This bug is fixed in version v0.28.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Conversion of property names to strings can trigger infinite recursion

msgpackr is a fast MessagePack NodeJS/JavaScript implementation. Prior to 1.10.1, when decoding user supplied MessagePack messages, users can trigger stuck threads by crafting messages that keep the decoder stuck in a loop. The fix is available in v1.10.1. Exploits seem to require structured cloning, replacing the 0x70 extension with your own (that throws an error or does something other than recursive referencing) should mitigate the issue.

Dompdf possible DoS caused by infinite recursion when parsing SVG images

Dompdf is an HTML to PDF converter for PHP. When parsing SVG images Dompdf performs an initial validation to ensure that paths within the SVG are allowed. One of the validations is that the SVG document does not reference itself. However, prior to version 2.0.4, a recursive chained using two or more SVG documents is not correctly validated. Depending on the system configuration and attack pattern this could exhaust the memory available to the executing process and/or to the server itself. php-svg-lib, when run in isolation, does not support SVG references for `image` elements. However, when used in combination with Dompdf, php-svg-lib will process SVG images referenced by an `image` element. Dompdf currently includes validation to prevent self-referential `image` references, but a chained reference is not checked. A malicious actor may thus trigger infinite recursion by chaining references between two or more SVG images. When Dompdf parses a malicious payload, it will crash due after exceeding the allowed execution time or memory usage. An attacker sending multiple request to a system can potentially cause resource exhaustion to the point that the system is unable to handle incoming request. Version 2.0.4 contains a fix for this issue.

Denial of service by abusing `fetchOptions.retry` in nuxt-api-party

`nuxt-api-party` is an open source module to proxy API requests. The library allows the user to send many options directly to `ofetch`. There is no filter on which options are available. We can abuse the retry logic to cause the server to crash from a stack overflow. fetchOptions are obtained directly from the request body. A malicious user can construct a URL known to not fetch successfully, then set the retry attempts to a high value, this will cause a stack overflow as ofetch error handling works recursively resulting in a denial of service. This issue has been addressed in version 0.22.1. Users are advised to upgrade. Users unable to upgrade should limit ofetch options.
