Title
Nmap 7.70 Denial of Service via XML Entity Expansion
Summary
Nmap 7.70 contains a denial of service vulnerability that allows local attackers to crash the application by processing malicious XML files with exponential entity expansion. Attackers can create a crafted XML file with nested entity definitions and open it through ZenMap's scan import functionality to cause the program to consume excessive system resources and crash.

GHSA-22P3-QRH9-CX32

Vulnerability from github – Published: 2022-06-29 21:51 – Updated: 2024-09-30 20:29
VLAI
Summary
URL previews of unusual or maliciously-crafted pages can crash Synapse media repositories or Synapse monoliths
Details

Impact

URL previews of some web pages can exhaust the available stack space for the Synapse process due to unbounded recursion. This is sometimes recoverable and leads to an error for the request causing the problem, but in other cases the Synapse process may crash altogether.

It is possible to exploit this maliciously, either by malicious users on the homeserver, or by remote users sending URLs that a local user's client may automatically request a URL preview for. Remote users are not able to exploit this directly, because the URL preview endpoint is authenticated.

Am I affected?

  • deployments with url_preview_enabled: false set in configuration are not affected.
  • deployments with url_preview_enabled: true set in configuration are affected.
  • deployments with no configuration value set for url_preview_enabled are not affected, because the default is false.

Patches

Administrators of homeservers with URL previews enabled are advised to upgrade to v1.61.1 or higher.

Workarounds

  • URL previews can be disabled in the configuration file by setting url_preview_enabled: false.
  • Deployments using workers can choose to offload URL previews to one or more dedicated worker(s), ensuring that a process crash does not disrupt other functionality of Synapse.

Summary
Jenkins Token Macro Plugin's recursive token expansion results in information disclosure and DoS
Details

Jenkins Token Macro Plugin recursively applied token expansion.

This could be used by users able to affect input to token expansion (such as change log messages), to inject additional tokens into the input, which would then be expanded, resulting in information disclosure (for example values of environment variables), or denial of service.

Most tokens have been changed to no longer recursively apply token expansion.

GHSA-247X-2F9F-5WP7

Vulnerability from github – Published: 2022-02-09 23:30 – Updated: 2024-11-13 22:14
VLAI
Summary
Stack overflow in TensorFlow
Details

Impact

The GraphDef format in TensorFlow does not allow self recursive functions. The runtime assumes that this invariant is satisfied. However, a GraphDef containing a fragment such as the following can be consumed when loading a SavedModel:

  library {
    function {
      signature {
        name: "SomeOp"
        description: "Self recursive op"
      }
      node_def {
        name: "1"
        op: "SomeOp"
      }
      node_def {
        name: "2"
        op: "SomeOp"
      }
    }
  }

This would result in a stack overflow during execution as resolving each NodeDef means resolving the function itself and its nodes.

Patches

We have patched the issue in GitHub commit 448a16182065bd08a202d9057dd8ca541e67996c.

The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

GHSA-24WQ-6X4V-Q3FV

Vulnerability from github – Published: 2026-06-26 21:32 – Updated: 2026-07-08 06:31
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

arm64: Reserve an extra page for early kernel mapping

The final part of [data, end) segment may overflow into the next page of init_pg_end[1] which is the gap page before early_init_stack[2]:

[1] crash_arm64_v9.0.1> vtop ffffffed00601000 VIRTUAL PHYSICAL ffffffed00601000 83401000

For 4K pages, the early kernel mapping may use 2MB block entries but the kernel segments are only 64KB aligned. Segment boundaries that fall within a 2MB block therefore require a PTE table so that different attributes can be applied on either side of the boundary.

KERNEL_SEGMENT_COUNT still correctly counts the five permanent kernel VMAs registered by declare_kernel_vmas(). However, since commit 5973a62efa34 ("arm64: map [_text, _stext) virtual address range non-executable+read-only"), the early mapper also maps [_text, _stext) separately from [_stext, _etext). This adds one more early-only split and can require one more page-table page than the existing EARLY_SEGMENT_EXTRA_PAGES allowance reserves.

Increase the 4K-page early mapping allowance by one page to cover that additional split.

}
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.
