Summary
nanoid: non-secure generators can loop indefinitely with negative size
Details

nanoid (Nano ID) before 5.1.16 contains an infinite loop in the customAlphabet and nanoid functions of its non-secure module (nanoid/non-secure). When these functions are given a negative size, the loop counter is decremented from a negative value and never reaches its termination condition, spinning indefinitely and hanging the calling thread. An application that passes an unvalidated, attacker-controlled negative size to these functions is exposed to a denial-of-service condition.

Summary
ORAS CLI: Cyclic Referrer Graph Can Cause Unbounded Recursion and Resource Consumption
Details

Summary

A malicious OCI registry can return a cyclic referrer graph (e.g. A -> A or A -> B -> A). The ORAS CLI's recursive referrer traversal does not track visited descriptors, so a cycle causes unbounded recursion and memory growth — a client-side denial of service.

This affects oras discover (recursive referrer traversal) and the recursive referrer counting used by oras backup and oras restore. Because oras discover --depth defaults to 0 (unlimited), discover is affected out of the box.

Note: This advisory covers only the ORAS CLI (oras.land/oras). The related Referrers API pagination loop in the oras-go library is tracked in a separate advisory on the oras-go repository.

Details

In oras discover, recursive referrer traversal follows discovered referrers without maintaining a visited-descriptor set.

Simplified flow:

runDiscover
  -> fetchAllReferrers(root)
     -> registry.Referrers(root)
     -> for each referrer:
          fetchAllReferrers(referrer)

A malicious registry can create cyclic graphs such as:

A -> A

or

A -> B -> A

Because traversal does not track previously visited descriptors, recursion never reaches a terminating condition.

Similarly, the recursive counting logic (graph.RecursiveFindReferrers, used by the backup and restore workflows) accumulates descriptors without cycle detection, causing unbounded memory growth.

PoC

Create valid descriptors where:

referrers(A) = [A]

or:

referrers(A) = [B]
referrers(B) = [A]

Run:

oras discover attacker.local/repo@sha256:<A>

The recursive traversal continues indefinitely, causing unbounded recursion and eventual resource exhaustion.

Impact

A malicious OCI registry can trigger client-side denial of service against ORAS CLI users and automation.

Potential impacts include:

  • Excessive CPU utilization
  • Excessive memory consumption
  • Unbounded recursion
  • Hung CI/CD jobs
  • Stalled automation pipelines
  • Failed backup or discovery operations

The issue does not enable arbitrary code execution, artifact substitution, or integrity bypass, but it can reliably prevent ORAS operations from completing when interacting with malicious registry metadata.

Patch

  • cmd/oras/root/discover.go — fetchAllReferrers threads a visited digest set; an already-traversed descriptor returns immediately, breaking cycles. Behavior is unchanged for valid (acyclic) referrer graphs.
  • internal/graph/graph.go — RecursiveFindReferrers tracks visited descriptors by digest and only recurses into unseen referrers, so traversal terminates on a cyclic graph.

Vulnerability from github – Published: 2026-09-05 21:31 – Updated: 2026-09-05 21:31

Details

libpcap BPF interpreter treats the offset in the 'ja L' BPF instruction as a signed integer to implement looping via backward jumps, but it does not limit the number of loop iterations. In particular uncommon use cases a crafted filter program can cause the interpreter to loop infinitely.

Vulnerability from github – Published: 2026-09-15 18:32 – Updated: 2026-09-15 18:32
VLAI
Details

FreeRDP versions before 3.31.0 contain an infinite-loop denial of service in the pool_decode_rect function when decoding AVC444 metablocks with more region rectangles than preallocated worker array size. A malicious RDP server can send crafted AVC444 graphics updates causing the threaded decode path to loop indefinitely, consuming CPU and preventing normal client operation.
