Security Bulletin: IBM CloudPak for Data Scheduling Service is vulnerable to CVE-2023-44487.
Summary The CPD Scheduling service uses Go lang, golang.org/x/net and gRPC-Go. CVE-2023-44487. Vulnerability Details CVEID:CVE-2023-44487 DESCRIPTION: The HTTP/2 protocol allows a denial of service server resource consumption because request cancellation can reset many streams quickly, as exploit...
golang: net/http: net/http: sensitive headers incorrectly sent after cross-domain redirect
A flaw was found in the net/http package of the Golang standard library. The HTTP client drops sensitive headers after following a cross-domain redirect. For example, a request to a.com/ containing an Authorization header redirected to b.com/ will not send that header to b.com. However, the...
net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME
A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...
net/http/internal/http2: golang: golang.org/x/net: Go HTTP/2: Denial of Service via malformed SETTINGS_MAX_FRAME_SIZE frame
A flaw was found in the HTTP/2 protocol implementation within the Go standard library golang.org/x/net and net/http/internal/http2. A remote attacker can exploit this vulnerability by sending a specially crafted HTTP/2 SETTINGS frame with the SETTINGSMAXFRAMESIZE parameter set to zero. This...
golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing
A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...
net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service
A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...
net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution
A flaw was found in net/url, a component of golang. This vulnerability arises when resolving relative paths that contain numerous parent directory '..' segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory...
net/mail: golang: Go net/mail: Denial of Service via crafted email inputs
A flaw was found in the net/mail package of the Go programming language. An attacker could provide specially crafted inputs to the ParseAddress, ParseAddressList, or ParseDate functions. This could lead to excessive consumption of CPU and memory resources, resulting in a Denial of Service DoS for...
net/mail: golang: net/mail: Denial of Service via pathological email address parsing
A flaw was found in the net/mail package within the Go standard library. A remote attacker could provide specially crafted, pathological email addresses. When these malformed email addresses are parsed by the consumePhrase function, it can lead to excessive resource consumption due to quadratic...
net/http: Sensitive headers not cleared on cross-origin redirect in net/http
A flaw was found in net/http. Handling Proxy-Authorization and Proxy-Authenticate headers during cross-origin redirects allows these headers to be inadvertently forwarded, potentially exposing sensitive authentication credentials. This flaw allows a network-based attacker to manipulate redirect...
net/http: golang: golang: Cross-user response poisoning via desynchronized HTTP CONNECT connections
A flaw was found in Go's net/http package. When an HTTP CONNECT request with a request body is rejected by a server, the client transport can desynchronize the connection before returning it to the shared idle pool. In shared reverse proxy environments, a remote attacker can exploit this issue to...
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...
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: net/http: HTTP request smuggling via improper handling of HTTP/1 CONNECT responses
A flaw was found in Go's net/http package. When an HTTP server sends a successful response to an HTTP/1 CONNECT request without taking raw control of the connection, it improperly continues to process incoming data as standard HTTP requests instead of establishing a tunnel. A remote attacker can...
net/textproto: mime/multipart: golang: golang: Denial of Service via memory limit bypass in multipart form parsing
A flaw was found in the mime/multipart and net/textproto packages in Go. A remote attacker could exploit this vulnerability by submitting a crafted multipart form request that bypasses configured memory limits when the remaining boundary limit is small. This issue allows the application to read a...
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: golang: golang: Denial of Service via crafted HTTP Range headers
A flaw was found in the Go net/http package. A remote attacker can cause a Denial of Service DoS by sending an HTTP request containing a Range header with a large number of small byte ranges. When the server processes these ranges while serving content, it consumes an excessive amount of CPU...
Important: Red Hat Security Advisory: go-toolset:rhel8 security, bug fix, and enhancement update
An update for the go-toolset:rhel8 module is now available for Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.6 Extended Update Support Long-Life Add-On. Red Hat Product Security has rated this update as having a security impact of Important. ...
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...
