Improper Handling of Highly Compressed Data (Data Amplification)

Overview Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data Data Amplification via the Decode function in the wire protocol when processing gzip-compressed messages. An attacker can cause excessive memory allocation and service unavailability by sendin...

CVE-2026-44160

Fluentd collects events from various data sources and writes them to files, RDBMS, NoSQL, IaaS, SaaS, Hadoop and so on. Prior to 1.19.3, Fluentd's inhttp and inforward plugins support gzip-compressed data but enforce limits only on compressed payloads through settings such as bodysizelimit and...

Unfurl's unbounded zlib decompression allows decompression bomb DoS

SummaryThe compressed data parser uses zlib.decompress without a maximum output size. A small, highly compressed payload can expand to a very large output, causing memory exhaustion and denial of service. Details- unfurl/parsers/parsecompressed.py calls zlib.decompressdecoded with no size limit.-...

urllib3 streaming API improperly handles highly compressed data

Impacturllib3'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.When streaming a compressed response, urllib3 can perform decoding or decompression based on the HTTP...

PYSEC-2026-1439 H2O Vulnerable to Denial of Service (DoS) via Large GZIP Parsing

In h2oai/h2o-3 version 3.46.0.2, a vulnerability exists where uploading and repeatedly parsing a large GZIP file can cause a denial of service. The server becomes unresponsive due to memory exhaustion and a large number of concurrent slow-running jobs. This issue arises from the improper handling...

Gradio Vulnerable to Denial of Service (DoS) via Crafted Zip Bomb

A vulnerability in the dataframe component of gradio-app/gradio version git 98cbcae allows for a zip bomb attack. The component uses pd.readcsv to process input values, which can accept compressed files. An attacker can exploit this by uploading a maliciously crafted zip bomb, leading to a server...

In aiohttp, compressed files as symlinks are not protected from path traversal

SummaryStatic routes which contain files with compressed variants .gz or .br extension were vulnerable to path traversal outside the root directory if those variants are symbolic links. DetailsThe server protects static routes from path traversal outside the root directory when followsymlinks=Fal...

PYSEC-2026-1108 In aiohttp, compressed files as symlinks are not protected from path traversal

Summary Static routes which contain files with compressed variants .gz or .br extension were vulnerable to path traversal outside the root directory if those variants are symbolic links. Details The server protects static routes from path traversal outside the root directory when...

USN-8512-1 gzip vulnerabilities

It was discovered that Gzip's gzexe utility handled temporary files in an insecure manner. When the mktemp utility was not available, gzexe constructed a temporary file path based on the process ID, which could be predicted. A local attacker could possibly use this issue to overwrite arbitrary...

OpenStack Nova denial of service through compressed disk images

OpenStack Compute Nova Folsom, Grizzly, and Havana does not properly verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service host file system disk consumption via a compressed QCOW2 image. NOTE: this issue is due to an incomplete fix for CVE-2013-2096...
