Apache bRPC resource management error vulnerability

Versions of Apache bRPC prior to 1.18.0 contain a resource management error vulnerability. This vulnerability arises because the HTTP/2 HPACK decoder fails to limit recursion depth. Remote attackers can exploit this by sending specially crafted HTTP/2 header blocks containing numerous consecutive...

Apache Traffic Server can be used to exhaust an HTTP/1.1 origin's worker pool via a truncated HTTP/2 Content-Length value. This issue affects Apache Traffic Server: from 8.0.0 through 8.1.11, from 9.0.0 through 9.2.15, from 10.0.0 through 10.1.4, 10.2.0. Users are recommended to upgrade to versio...

A reachable-assertion flaw in the HPACK header-compression decoder of the HTTP/2 h2/gRPC stack in Apache bRPC version = 1 byte + value = 1 byte + 32 bytes of overhead. However, RFC 7541 section 4.1 specifies that the minimum entry size is 33 bytes, because the value may be empty name = 1 byte +...

Apache bRPC buffer error vulnerability

A security vulnerability exists in Apache bRPC versions prior to 1.18.0. This vulnerability stems from integer underflow and out-of-bounds reads during the parsing of HTTP/2 DATA frames, potentially allowing unauthenticated remote attackers to send malformed DATA frames and induce a...

Apache bRPC resource management error vulnerability

Versions of Apache bRPC prior to 1.18.0 contain a resource management error vulnerability. This vulnerability arises from the failure to consistently enforce the configured maxbodysize limit during non-persistent HTTP/1 and HTTP/2 parsing, as well as in parsing responses from memcache and...

Apache bRPC resource management error vulnerability

Versions of Apache bRPC prior to 1.18.0 contain a security vulnerability. This vulnerability arises because the HTTP/2 h2 receive path fails to enforce endpoint restrictions such as SETTINGSMAXCONCURRENTSTREAMS and SETTINGSMAXHEADERLISTSIZE. As a result, write limits on control frames are bypasse...

Interpretation conflict in the HTTP protocol implementation in Apache bRPC version 1.18.0 on all platforms allows remote attackers to bypass access control rules enforced by a front proxy. Root Cause: The method dispatch function FindMethodPropertyByURI in bRPC's HTTP protocol splits the request...

net/http: net/http/internal/http2: golang: golang.org/x/net/http2: net/http: Denial of Service via concurrent HPACK encoder modification

A flaw was found in Go's net/http package. A remote attacker can cause a Denial of Service DoS by crashing the HTTP/2 server. Due to missing synchronization, the server concurrently modifies its HPACK HTTP/2 header compression encoder when encoding response headers while processing incoming table...

net/http: net/http/internal/http2: golang: golang.org/x/net/http2: golang: flow control limit bypass via double refund in HTTP/2 server

A flaw was found in Go's HTTP/2 server implementation. A remote attacker can bypass connection-level flow control limits—mechanisms that regulate incoming network data—potentially causing excessive memory consumption and a Denial of Service DoS. This issue occurs because the server improperly...

net/http: net/http/internal/http2: golang.org/x/net/http2: net/http: Denial of Service via excessive HTTP/2 SETTINGS frames

A flaw was found in the Go net/http package. This flaw allows a remote attacker to cause a Denial of Service DoS by triggering excessive CPU consumption on an affected client or server. By opening a large number of HTTP/2 streams and repeatedly sending small configuration SETTINGS frames that...

net/http: golang: golang.org/x/net/http2: net/http: HTTP response smuggling via malformed HTTP/2 framing headers

A flaw was found in Go's net/http package. When operating as a reverse proxy, the HTTP/2 implementation does not properly validate framing-related headers in responses received from upstream servers before forwarding them to downstream HTTP/1 clients. A malicious upstream server can exploit this...

net/http: golang.org/x/net/http2: golang: net/http: Denial of Service via HTTP/2 trailer header memory exhaustion

A flaw was found in the Go net/http package. A remote attacker can trigger a Denial of Service DoS by sending HTTP/2 requests that declare an excessive number of trailer header fields. Because the server bypasses configured header limits when allocating memory for these declarations, an attacker...
