urllib3: urllib3 vulnerable to decompression-bomb safeguard bypass when following HTTP redirects (streaming API)

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 based on the HTTP...

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...

UBUNTU-CVE-2026-53539

Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.30, when parsing application/x-www-form-urlencoded bodies, QuerystringParser located the field separator with a two step lookup: it first scanned the entire remaining buffer for &, and only when no & existed anywhere ahead...

UBUNTU-CVE-2026-53540

Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.31, parseform did not validate the Content-Length header before using it to bound its chunked read of the request body. A negative Content-Length turned the bounded read into a read-until-EOF, so the entire body was loaded...

UBUNTU-CVE-2026-53538

Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.30, QuerystringParser treated ; as a field separator in application/x-www-form-urlencoded bodies, in addition to &. The WHATWG URL standard, modern browsers, and Python's urllib.parse since the CVE-2021-23336 fix treat only...

UBUNTU-CVE-2026-53537

Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.30, parseoptionsheader parsed Content-Disposition and Content-Type headers with email.message.Message, which transparently applies RFC 2231/5987 decoding. The extended parameter syntax filename=charset'lang'value, name=...,...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted sequence of H.265 NAL units causes...

Linux Distros Unpatched Vulnerability : CVE-2026-9375

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - urllib3 version 2.6.3 is vulnerable to a decompression bomb bypass in its streaming API preloadcontent=False when using Brotli support. The issue arises due to...

MessagePack for Python: Out-of-bounds read / crash on Unpacker reuse after a caught error

Impact If the Unpacker is used repeatedly after an error occurs, the process may crash with a SEGV. If the Unpacker is used repeatedly to unpack untrusted input from external sources, it may be vulnerable to a DoS attack. Patches v1.2.1 Workarounds Users should create a new Unpacker instead of...

CVE-2026-49337

CVE-2026-49337 affects libde265 prior to 1.0.20. A crafted sequence of H.265 NAL units lets decoder_context::read_slice_NAL() attach slice headers to a finished picture object with no active image unit, causing attacker-controlled unbounded heap growth. The headers are retained until the picture ...

CVE-2026-9375 Decompression Bomb Bypass via Negative max_length in Streaming API in urllib3

urllib3 version 2.6.3 is vulnerable to a decompression bomb bypass in its streaming API preloadcontent=False when using Brotli support. The issue arises due to three independent code paths in response.py that bypass the maxlength protection introduced in version 2.6.0 to mitigate CVE-2025-66471...

CVE-2026-48138

There is an out-of-bounds read vulnerability in the NI grpc-device streaming API due to a missing bounds check that may result in a denial of service. Successful exploitation requires an attacker to supply a specially crafted write request. This affects NI grpc-device 2.17.0 and prior versions...
