io.netty/netty-codec-http2: Netty: Denial of Service via HTTP/2 DATA frame memory leak

A flaw was found in Netty, a network application framework. A remote, unauthenticated attacker can exploit this vulnerability by sending specially crafted HTTP/2 DATA frames to applications that use Netty and have HTTP/2 content decompression enabled. This can lead to memory exhaustion, causing t...

netty: io.netty/netty-codec-http: Netty: Denial of Service via SPDY header decompression amplification

A flaw was found in Netty, a network application framework. A remote attacker could exploit a vulnerability in the SPDY header decoding process. By sending a specially crafted, small compressed header block, the attacker can cause it to expand significantly during decompression, leading to...

CVE-2026-106585: Improper Handling of Highly Compressed Data (Data Amplification)

In sshd and ssh in OpenSSH before 10.6, there is no check for whether the maximum packet length is exceeded during decompression of highly compressed data...

PT-2026-107283

Name of the Vulnerable Software and Affected Versions OpenSSH versions prior to 10.6 Description The sshd and ssh components fail to verify if the maximum packet length is exceeded when decompressing highly compressed data. Recommendations Update to version 10.6 or later...

keycloak: Keycloak: Denial of Service due to excessive SAMLRequest decompression

A flaw was found in Keycloak. An unauthenticated remote attacker can trigger an application level Denial of Service DoS by sending a highly compressed SAMLRequest through the SAML Redirect Binding. The server fails to enforce size limits during DEFLATE decompression, leading to an OutOfMemoryErro...

Astra Linux – Vulnerability in curl

curl 7.84.0 supports “chained” HTTP compression algorithms, which means that a server response can be compressed multiple times, possibly using different algorithms. The number of allowable “links” in this “decompression chain” is unlimited, allowing a malicious server to insert virtually an...

Astra Linux – Vulnerability in curl

There is a vulnerability in curl v7.88.0 where resource allocation without limits or throttling exists. This vulnerability stems from the “chained” HTTP compression algorithms. This means that a server’s response can be compressed multiple times, possibly using different algorithms. The number of...

Astra Linux – Vulnerability in Ruby 2.5

The attack vector is a potential Denial of Service DoS attack. The vulnerability arises from an insufficient check on the length of a decompressed domain name within a DNS packet. An attacker can create a malicious DNS packet containing a highly compressed domain name. When the resolv library...

Astra Linux – Vulnerability in docker.io-app

Moby is an open-source container framework. In versions prior to 29.5.1, as well as in moby/moby v2 before v2.0.0-beta.14, when a compressed archive was uploaded to a container via PUT /containers/id/archive or piped through docker cp -, the daemon would resolve the decompression binaries such as...

Astra Linux – Vulnerability in openexr

A flaw was discovered in OpenEXR in versions prior to 3.0.0-beta. A specially crafted input file provided by an attacker, when processed by the Dwa decompression functionality of OpenEXR’s IlmImf library, could lead to a NULL pointer dereferencing error. The most severe consequence of this...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Check whether more than chunksize bytes are written. An incorrectly formatted chunk may be decompressed into more than LZNTCHUNKSIZE bytes, and an out-of-bounds index will occur in smaxoff...

SUSE-SU-2026:4444-1 Security update for terraform-provider-susepubliccloud

This update for terraform-provider-susepubliccloud fixes the following issues: - CVE-2026-84303: google.golang.org/grpc: xDS RBAC HTTP filter implementation issue allows for bypass of authorization policies via mixed-case or canonical-case header matches bsc1279252. - CVE-2026-84304:...

CVE-2026-94637

A flaw was found in the Apache Thrift Go library. A remote attacker could exploit this vulnerability by submitting specially crafted, highly compressed data to an affected service. Due to improper handling during decompression, the resulting data amplification can exhaust system resources, leadin...

Data Amplification

Overview thrift is a Python bindings package for Apache Thrift. Affected versions of this package are vulnerable to Data Amplification in TZlibTransport, whose decompressed size limit stops being enforced once the limit has been exactly consumed, so decompression past that point proceeds unbounde...

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 in the decompression. An attacker can exhaust system resources and render the service unavailable by sending specially crafted, highly compressed data payloads. Remediation...

CVE-2026-53716

A flaw was found in Envoy Gateway. A remote attacker, by providing a specially crafted compressed WebAssembly Wasm payload through a tenant-controlled URL, can exploit a vulnerability where the system decompresses the gzip file without limiting the output size. This can lead to an uncontrolled...

PYSEC-2026-4182 Zapros: Streaming decoders ignored the requested chunk size, allowing a single compressed response chunk to allocate unbounded memory (decompression bomb)

Impact Denial of service via memory exhaustion. Affects all callers who streamed compressed responses relying on the chunk size — explicit iterbyteschunksize=... or the default — to bound memory. The decoder ignored that bound, so a chunk could be far larger than requested and a single compressed...

PYSEC-2026-4181 Zapros has an Unbounded Content-Encoding decompression chain that allows denial of service

Impact Who is impacted: - Any application using Zapros to make HTTP requests to untrusted servers - Applications that follow redirects to attacker-controlled hosts Attack vector: - A malicious HTTP server returns a response with many chained content encodings. When the client attempts to decode, ...
