CVE-2023-33953

CVE-2023-33953 concerns the gRPC HPACK parser. Multiple vectors cause denial-of-service via: (1) unbounded memory buffering due to header size checks behind string reads, (2) unbounded CPU due to per-input-block memory copies creating an 0(n^2) parsing loop, (3) HPACK varints that can start with ...

Important: grpc

Issue Overview: When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame. This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables between sender and receiver. If leveraged, say, between a proxy and...

Security Bulletin: IBM Watson Discovery Cartridge for IBM Cloud Pak for Data affected by vulnerability in gRPC

Summary IBM Watson Discovery Cartridge for IBM Cloud Pak for Data contains a vulnerable version of gRPC. Vulnerability Details CVEID:CVE-2023-32732 DESCRIPTION: gRPC is vulnerable to a denial of service, caused by a base64 encoding error for "-bin" suffixed headers. By sending a specially crafted...

Denial Of Service (DoS)

github.com/envoyproxy/envoy is vulnerable to Denial of Service DoS attacks. When the listener is exhausted, gRPC access logs utilizing its global scope may result in a use-after-free, which allows an authenticated attacker to cause an application crash via a malicious LDS upstream...

CVE-2023-35942

A flaw was found in Envoy, where gRPC access loggers using the listener's global scope can cause a use-after-free crash when the listener is drained. This issue can be triggered by a listener discovery service LDS update with the same gRPC access log configuration...
