Summary
SQLFluff: Recursive Stack Overflow in Parser
Details

Impact

In deployments where untrusted users can provide SQL queries to be linted, an untrusted user can submit a malicious query with deliberate excessive nesting to any application using the parser to trigger a Denial of Service through resource exhaustion.

Patches

Versions 4.1.0 and up contain a configurable recursion limit, which is enabled by default, to prevent this manner of exploit.

Summary
Excelize ANCHORARRAY: mutually-referencing array formulas recurse unboundedly via re-entrant CalcCellValue, causing a fatal stack overflow
Details

Summary

ANCHORARRAY (calc.go:15137 on current master) evaluates each cell of the referenced spill range by calling the exported CalcCellValue, which unconditionally constructs a fresh calcContext — fresh entry marker, fresh iterations map, full MaxCalcIterations budget (calc.go:896-900). The circular-reference control only exists within one context: the entry-exclusion marker and per-ref iteration budget are fields of that single context, and completion-based caching (formulaArgCache/calcRawCache) only ever stores results of evaluations that finish.

During a pure cycle no nested evaluation ever finishes, so nothing is ever cached to break the recursion, and each hop re-arms the entire budget. Two ordinary, Excel-legal constructs in an attacker-supplied workbook are enough:

  • A1 (dynamic array formula, ref A1:A1): _xlfn.ANCHORARRAY($B$1)
  • B1 (dynamic array formula, ref B1:B1): _xlfn.ANCHORARRAY($A$1)

→ CalcCellValue → calcCellValue → evalInfixExp → parseReference → cellResolver → … → ANCHORARRAY → CalcCellValue → … forever, ending in a fatal, unrecoverable Go runtime error: runtime: goroutine stack exceeds …-byte limit / fatal error: stack overflow. Go stack overflows cannot be recovered — the whole process aborts.

Details

  • The terminating edge the iterations gate is supposed to provide does not exist across contexts: there is no in-flight tracking shared between nested CalcCellValue calls.
  • Both formulas are ordinary Excel-legal constructs; no exotic XML is required.
  • Excelize's own APIs reach formula evaluation on untrusted cells implicitly (e.g. pivotTable.go:538, picture.go:985/1141, col.go:892), so a service that merely adds a pivot table or a picture over such a workbook dies.
  • No option value prevents it: MaxCalcIterations is irrelevant because every hop gets a fresh budget.
  • Measured: a 64 MB stack budget is exhausted in ~0.09 s; the ~1 GB default in ~1–2 s.

PoC

A standalone program (public API only) was provided to the maintainer by email (4-anchorarray-recursion): NewFile + SetCellFormula with FormulaOpts{Type: array, Ref: A1:A1 / B1:B1}, then CalcCellValue("Sheet1","A1"). On master ecd99d761fe0 (2026-09-08) the process aborts with fatal error: stack overflow; with the proposed patch the cycle terminates normally (CYCLE_TERMINATED) and existing calc tests pass.

Impact

An attacker ships a workbook containing the two formulas; any service that evaluates a formula over those cells — directly via CalcCellValue, or implicitly via AddPivotTable / AddPicture / auto-fit — aborts. Remote, unauthenticated, process-fatal, no configuration prevents it.

Proposed fix

Evaluate spill-range cells through the current calculation context — fn.f.cellResolver(fn.ctx, …) instead of the exported CalcCellValue — so the entry check and iterations gate of the running calculation apply. cellResolver returns the typed value directly (dropping a string round-trip); an ArgEmpty → "" shim preserves the existing ToNumber behavior for empty spill cells, and a fresh-context fallback covers the legacy nil-ctx test paths. A complete patch has been provided to the maintainer.

Uncontrolled recursion in DcmDicomDir::moveRecordToTree() in dcmdata/libsrc/dcdicdir.cc of OFFIS DCMTK 3.7.0 allows an attacker to cause a denial of service (stack exhaustion and process crash) via a crafted DICOMDIR file with a deeply chained sequence of directory records linked through the Offset of Referenced Lower-Level Directory Entity attribute. Any application that opens the DICOMDIR is affected, including dcmgpdir and media viewers built on DCMTK. The issue is fixed in commit ca761f7f3dcaaddaa95be87cf5d736138d7c3a9f.

Vulnerability from github – Published: 2026-06-10 00:31 – Updated: 2026-06-10 00:31

Details

A vulnerability in MongoDB Server's BSON validation logic allows an unauthenticated user to crash the mongod process by sending a specially crafted message. The BSON validator's handling of certain nested binary data structures permits uncontrolled mutual recursion between validation functions, where each re-entry resets internal depth tracking.

Vulnerability from github – Published: 2026-06-04 18:30 – Updated: 2026-06-04 21:31
VLAI
Details

Net::CIDR::Set versions through 0.20 for Perl did not validate IP addresses.

The add method called the _encode method to parse addresses. If the addresses did not look like netmasks or network ranges, then they were assumed to single IP addresses and passed back to itself as a 32-bit or 128-bit netmask.

If the argument was not a well-formed IP address, then this would lead to indefinite recursion.

An attacker could use this to cause a denial of service.

Vulnerability from github – Published: 2022-05-13 01:12 – Updated: 2022-05-13 01:12
VLAI
Details

Receipt of a malformed packet on MX Series devices with dynamic vlan configuration can trigger an uncontrolled recursion loop in the Broadband Edge subscriber management daemon (bbe-smgd), and lead to high CPU usage and a crash of the bbe-smgd service. Repeated receipt of the same packet can result in an extended denial of service condition for the device. Affected releases are Juniper Networks Junos OS: 16.1 versions prior to 16.1R7-S1; 16.2 versions prior to 16.2R2-S7; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R3; 17.3 versions prior to 17.3R3-S1; 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R3; 18.2 versions prior to 18.2R2.

}
Mitigation
Implementation

Ensure that an end condition will be reached under all logic conditions. The end condition may include checking against the depth of recursion and exiting with an error if the recursion goes too deep. The complexity of the end condition contributes to the effectiveness of this action.

Mitigation
Implementation

Increase the stack size.

CAPEC-230: Serialized Data with Nested Payloads

Applications often need to transform data in and out of a data format (e.g., XML and YAML) by using a parser. It may be possible for an adversary to inject data that may have an adverse effect on the parser when it is being processed. Many data format languages allow the definition of macro-like structures that can be used to simplify the creation of complex structures. By nesting these structures, causing the data to be repeatedly substituted, an adversary can cause the parser to consume more resources while processing, causing excessive memory consumption and CPU utilization.

CAPEC-231: Oversized Serialized Data Payloads

An adversary injects oversized serialized data payloads into a parser during data processing to produce adverse effects upon the parser such as exhausting system resources and arbitrary code execution.
