Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write through recursive calls to the eachchild function when processing deeply nested input. An attacker can cause the process to crash and trigger a denial of service by supplying a specially crafted, deeply nested JSON...

GHSA-3M6Q-JJ5J-38C9 Oj: Stack Buffer Overflow in Oj::Doc#each_child via Deeply Nested Input

Summary Oj::Doceachchild, when invoked recursively over a deeply nested JSON document, overflows a fixed-size stack buffer and aborts the process. This is a denial of service reachable from untrusted JSON. Details Two-step chain in ext/oj/fast.c: 1. doceachchild line 1501 increments doc-where pas...

Faraday: Uncontrolled recursion in NestedParamsEncoder allows stack exhaustion DoS via deeply nested query parameters

Faraday::NestedParamsEncoder, the default nested query parameter encoder/decoder in Faraday, decodes nested query strings without enforcing a maximum nesting depth. A crafted query string such as: text axxxx...x=1 causes Faraday to build a deeply nested Ruby Hash structure. The internal dehash...

Unauthenticated nested page API leaks restricted & unpublished content - Location: app/controllers/alchemy/api/pagescontroller.rb:28 Api::PagesControllernested - Affected version: Alchemy CMS 8.3.0.dev Rails 8.1.3 Description The unauthenticated GET /api/pages/nested endpoint returns the full pag...

Inefficient Algorithmic Complexity

Overview parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js. Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity through the query-depth processing in validateQueryDepth and...

GHSA-CGXM-VR2F-6FJ8 parse-server: Denial of service via exponential-time processing of deeply nested query operators

Impact Parse Server is vulnerable to denial of service. A remote attacker can send a single, small query 1 KB containing deeply nested query condition operators. Parse Server processes the nested structure with exponential time complexity, which blocks the Node.js event loop and makes the server...

Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in the AMD nested virtualization SVM feature of the KVM. A malicious L1 guest could intentionally fail to intercept the shutdown of a cooperative nested guest L2, potentially causing a page fault and kernel panic in the host L0...

Astra Linux – Vulnerability in Linux 5.15

A race condition in the x86 KVM subsystem within the Linux kernel, as of 6.1-rc6, allows guest OS users to cause a denial of service host OS crash or host OS memory corruption when nested virtualization is enabled and the TDP MMU is also enabled...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Stopping the IRR scan in kvmapicupdateirr even if PIR is empty The function apicfindhighestvector is used when PID.ON is set, but PIR turns out to be empty. This ensures that the highest pending interrupt from the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM – Avoid clearing VMCBLBR in vmcb12. The svmcopylbrs function always marks VMCBLBR as dirty in the destination VMC. However, nestedsvmvmexit uses it to copy LBRs to vmcb12, and clearing the “clean” bits in vmcb12 is not...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: KVM: x86 – Check for nEPT/nNPT in slow flush hypercalls The check for isguestmodevcpus is incorrect, because the translatenestedgpa function is only valid if a L2 guest is running with nested EPT/NPT enabled. Instead, use the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Raise UD if the unhandled VMMCALL is not intercepted by L1. If L2 is active, and L1 does not want to intercept VMMCALL, and nestedsvml2tlbflush is enabled, and the hypercall is something other than one of the supported...

netty-codec-haproxy: Netty HAProxy PROXY protocol v2 codec: Denial of Service via memory leak from crafted PROXY protocol headers

A flaw was found in the Netty HAProxy PROXY protocol v2 codec. A remote attacker can exploit this vulnerability by sending a specially crafted HAProxy PROXY protocol v2 header with nested PP2TYPESSL type-length-value TLV records. This can lead to a memory leak, causing the underlying cumulation...
