Name of the Vulnerable Software and Affected Versions: Android versions Android-12L Description: In the getAppSize function of InstalldNativeService.cpp, there is a possible out of bounds read due to a missing bounds check. This could lead to local escalation of privilege with System execution...

GHSA-RMPJ-7C96-MRG8 Apache Hadoop heap overflow before v2.10.2, v3.2.3, v3.3.2

There is a potential heap buffer overflow in Apache Hadoop libhdfs native code. Opening a file path provided by user without validation may result in a denial of service or arbitrary code execution. Users should upgrade to Apache Hadoop 2.10.2, 3.2.3, 3.3.2 or higher...

CVE-2022-29225

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 secompressors accumulate decompressed data into an intermediate buffer before overwriting the body in the decode/encodeBody. This may allow an attacker to zip bomb the decompressor by sending a small highly compressed...

Design/Logic Flaw

Envoy is a cloud-native high-performance edge/middle/service proxy. In versions prior to 1.22.1 if Envoy attempts to send an internal redirect of an HTTP request consisting of more than HTTP headers, there’s a lifetime bug which can be triggered. If while replaying the request Envoy sends a loc...

Design/Logic Flaw

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 the OAuth filter would try to invoke the remaining filters in the chain after emitting a local response, which triggers an ASSERT in newer versions and corrupts memory on earlier versions. continueDecoding shouldn’t eve...

Authentication flaw

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 the OAuth filter implementation does not include a mechanism for validating access tokens, so by design when the HMAC signed cookie is missing a full authentication flow should be triggered. However, the current...

CVE-2022-29227 Use after free in Envoy

Envoy is a cloud-native high-performance edge/middle/service proxy. In versions prior to 1.22.1 if Envoy attempts to send an internal redirect of an HTTP request consisting of more than HTTP headers, there’s a lifetime bug which can be triggered. If while replaying the request Envoy sends a local...

CVE-2022-29227

Envoy has a use-after-free in versions before 1.22.1 triggered when replaying an HTTP request with an internal redirect that contains more than the HTTP headers; if a local reply is emitted while redirect headers are processed and the downstream state marks the stream incomplete, Envoy attempts t...

CVE-2022-29225

CVE-2022-29225 affects Envoy where secompressors in versions before 1.22.1 accumulate decompressed data and overwrite the body during decode/encode, potentially allowing a zip bomb attack that exhausts memory and causes DoS. The connected sources confirm this behavior and the advised mitigation i...

Null pointer dereference

Envoy is a cloud-native high-performance proxy. Versions of envoy prior to 1.22.1 are subject to a segmentation fault in the GrpcHealthCheckerImpl. Envoy can perform various types of upstream health checking. One of them uses gRPC. Envoy also has a feature which can “hold� prevent removal...

Caller always pays for ETH even for ETH offer items

Lines of code Vulnerability details Impact It's possible to create ItemType.NATIVE offer items that the offerer should pay for but this is not possible as only the caller fulfiller can send native tokens ETH when fulfilling an order. Therefore, this item type does not make sense in an offer. The...
