freerdp: FreeRDP: Heap buffer overflow leading to denial of service and potential code execution from a malicious server.

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. This vulnerability occurs because the freerdpbitmapdecompressplanar function does not properly validate bitmap dimensions when decompressing planar bitmap data. A malicious server can exploit this by sending...

Scrapy: python-scrapy: brotli: Python brotli decompression bomb DoS

Scrapy are vulnerable to a denial of service DoS attack due to a flaw in its brotli decompression implementation. The protection mechanism against decompression bombs fails to mitigate the brotli variant, allowing remote servers to crash clients with less than 80GB of available memory. This occur...

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: python3.13-pip

Issue Overview: urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression...

Medium: 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...
