Denial of Service (DoS)

Overview magento/community-edition is a modern cloud eCommerce platform. Affected versions of this package are vulnerable to Denial of Service DoS through the handling of resource requests. An attacker can cause the application to become unresponsive by sending specially crafted requests that...

CVE-2026-43469

A flaw was found in the Linux kernel's xprtrdma component. This vulnerability occurs when the rpcrdmapostrecvs function fails to create a work request or exits prematurely, leading to the rereceiving counter not being decremented. This improper resource handling can cause the system to hang...

Memory Allocation with Excessive Size Value

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value through the UploadTraces, UploadMetrics, and uploadLogs response-handling paths in exporters/otlp/otlptrace/otlptracehttp/client.go, exporters/otlp/otlpmetric/otlpmetrichttp/client.go, and...

Denial Of Service

pypdf is vulnerable to Denial of Service. The vulnerability is due to inefficient decoding of array-based streams, where accessing an array-based stream with many entries leads to long runtimes and large memory usage, and attackers can exploit it by crafting a malicious PDF with a large array-bas...

UBUNTU-CVE-2026-33123

pypdf is a free and open-source pure-python PDF library. Versions prior to 6.9.1 allow an attacker to craft a malicious PDF which leads to long runtimes and/or large memory usage. Exploitation requires accessing an array-based stream with many entries. This issue has been fixed in version 6.9.1...

pypdf 安全漏洞

pypdf is an open-source, free Python library for handling PDF files. It allows for splitting, merging, cropping, and converting pages within PDF files.

urllib3: urllib3 Streaming API improperly handles highly compressed data

A decompression handling flaw has been discovered in urllib3. When streaming a compressed response, urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header e.g., gzip, deflate, br, or zstd. The library must read compressed data from the network and decompress it...

Important: python-urllib3

Issue Overview: urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.24 and prior to 2.6.0, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps leading to high CPU usage an...
