GHSA-WX95-C6CV-8532

Vulnerability from github – Published: 2026-02-18 21:57 – Updated: 2026-09-02 14:42
VLAI
Summary
Nokogiri does not check the return value from xmlC14NExecute
Details

Summary

Nokogiri's CRuby extension fails to check the return value from xmlC14NExecute in the method Nokogiri::XML::Document#canonicalize and Nokogiri::XML::Node#canonicalize. When canonicalization fails, an empty string is returned instead of raising an exception. This incorrect return value may allow downstream libraries to accept invalid or incomplete canonicalized XML, which has been demonstrated to enable signature validation bypass in SAML libraries.

JRuby is not affected, as the Java implementation correctly raises RuntimeError on canonicalization failure.

Mitigation

Upgrade to Nokogiri >= 1.19.1.

Severity

The maintainers have assessed this as Medium severity. Nokogiri itself is a parsing library without a clear security boundary related to canonicalization, so the direct impact is that a method returns incorrect data on invalid input. However, this behavior was exploited in practice to bypass SAML signature validation in downstream libraries (see References).

Credit

This vulnerability was responsibly reported by HackerOne researcher d4d.

GHSA-X2HF-3RGR-R89X

Vulnerability from github – Published: 2026-09-02 03:31 – Updated: 2026-09-02 03:31
VLAI
Details

In FIPS mode, Libreswan's add_decoded_cert() function calls CERT_ExtractPublicKey() and asserts that the result is not NULL. However, CERT_ExtractPublicKey() returns NULL when public key extraction fails, for example if the RSA exponent is set to 0. A remote attacker can send a malformed X.509 certificate in a CERT payload to trigger the assertion, causing the pluto daemon to abort and restart. Continued exploitation causes a denial of service. No remote code execution is possible. Both IKEv1 and IKEv2 are affected. The vulnerability is only exploitable when both the OS and libreswan are running in FIPS mode and at least one CA certificate is loaded. The CERT payload is processed before peer authentication, so no credentials are needed to exploit this. Configurations using only PreSharedKey (PSK) authentication with no CA certificates loaded in the NSS database are not vulnerable.

Vulnerability from github – Published: 2022-12-08 16:12 – Updated: 2022-12-09 15:21
VLAI
Summary
go-merkledag's ProtoNode may be modified such that common method calls may panic
Details

Impact

A ProtoNode may be modified in such a way as to cause various encode errors which will trigger a panic on common method calls that don't allow for error returns.

A ProtoNode should only be able to encode to valid DAG-PB, attempting to encode invalid DAG-PB forms will result in an error from the codec. Manipulation of an existing (newly created or decoded) ProtoNode using the modifier methods did not account for certain states that would place the ProtoNode into an unencodeable form.

Due to conformance with the github.com/ipfs/go-block-format#Block and github.com/ipfs/go-ipld-format#Node interfaces, certain methods, which internally require a re-encode if state has changed, will panic due to the inability to return an error.

Additionally, use of the ProtoNode#SetCidBuilder() method to set a non-functioning CidBuilder (such as one that refers to a multihash where an implementation of that hash function is not available) may cause the same methods to panic as a new CID is required but cannot be created.

Patches

Releases involving fixes for this issue are v0.8.0 and v0.8.1. The recommended minimum version is v0.8.1.

  • Additional checks are performed on ProtoNode state changes to avoid the possibility of creating unencodeable forms, errors are returned where this is the case.
  • The builder passed in to SetCidBuilder() is inspected to attempt to determine if it is usable to generate CIDs, otherwise an error is returned.
  • The panics have been removed and replaced with default values (empty byte slice for RawData() and a default zero-bytes DAG-PB CID for methods involving CIDs).

Workarounds

These workarounds are available when using impacted versions to avoid panic conditions, and may be generally appropriate in order to provide meaningful feedback to users and avoid generating bad, or unexpected encoded data:

  • Sanitise inputs when allowing user-input to set a new CidBuilder on a ProtoNode.
  • Sanitise Tsize (Link#Size) values such that they are a reasonable byte-size for sub-DAGs where derived from user-input.

Summary
Duplicate Advisory: Nokogiri does not check the return value from xmlC14NExecute
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-wx95-c6cv-8532. This link is maintained to preserve external references.

Original Description

Nokogiri versions before 1.19.1 fail to check the return value from xmlC14NExecute in the canonicalize method, returning an empty string on failure instead of raising an exception. Attackers can exploit this to bypass signature validation in downstream SAML libraries by providing invalid canonicalized XML that is incorrectly accepted as valid.

GHSA-XRR8-P4PF-HFWR

Vulnerability from github – Published: 2025-04-16 15:34 – Updated: 2026-06-19 15:33
VLAI
Details

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

nfsd: don't ignore the return code of svc_proc_register()

Currently, nfsd_proc_stat_init() ignores the return value of svc_proc_register(). If the procfile creation fails, then the kernel will WARN when it tries to remove the entry later.

Fix nfsd_proc_stat_init() to return the same type of pointer as svc_proc_register(), and fix up nfsd_net_init() to check that and fail the nfsd_net construction if it occurs.

svc_proc_register() can fail if the dentry can't be allocated, or if an identical dentry already exists. The second case is pretty unlikely in the nfsd_net construction codepath, so if this happens, return -ENOMEM.

Mitigation MIT-53
Implementation

Check the results of all functions that return a value and verify that the value is expected.

Mitigation MIT-56
Implementation

For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].

Mitigation
Implementation

Ensure that you account for all possible return values from the function.

Mitigation
Implementation

When designing a function, make sure you return a value or throw an exception in case of an error.
