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/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...
encoding/xml: golang: Go: Denial of Service via XML decoding recursion depth issue
A flaw was found in the encoding/xml package of Go. The DecodeElement function failed to correctly track recursion depth, which could lead to stack exhaustion. A remote attacker could exploit this vulnerability by providing a specially crafted XML input, resulting in a Denial of Service DoS for t...
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...
crypto/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages
A flaw was found in the crypto/tls package, part of golang. A malicious client can exploit this vulnerability by continuously sending KeyUpdate messages to a server. This forces the server to perform indefinite key derivation operations, leading to resource exhaustion and a Denial of Service DoS...
html/template: golang: golang: cross-site scripting via consecutive expressions in JavaScript template literals
A flaw was found in the html/template package in Go. This vulnerability allows a remote attacker to conduct cross-site scripting XSS, an attack that executes malicious scripts in a user's browser through improper output escaping. When a JavaScript template literal contains consecutive expressions...
crypto/tls: golang: crypto/tls: Denial of Service via multiple ECH outer extension references
A flaw was found in crypto/tls. A remote attacker can trigger this vulnerability by sending a specially crafted packet containing multiple Encrypted Client Hello ECH outer extension references to a server. Processing these unauthorized references leads to excessive memory consumption, causing a...
golang: internal/syscall/unix: Root.Chmod can follow symlinks out of the root
A flaw was found in the internal/syscall/unix package in the Go standard library. If the target of the Root.Chmod function is replaced with a symbolic link during execution, specifically after Root.Chmod checks the target but before acting, the chmod operation will be performed on the file the...
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...
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...
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/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...
crypto/internal/nistec: golang: Timing sidechannel for P-256 on ppc64le in crypto/internal/nistec
A flaw was found in the Golang crypto/internal/nistec package. Due to the usage of a variable time instruction in the assembly implementation of an internal function, a small number of bits of secret scalars are leaked on the ppc64le architecture. Considering how this function is used, this leaka...
crypto/x509: Incorrect enforcement of email constraints in crypto/x509
A certificate validation flaw has been discovered in the golang crypto/x509 module. When verifying a certificate chain which contains a certificate containing multiple email address constraints which share common local portions but different domain portions, these constraints will not be properly...
golang: cmd/compile: possible memory corruption after bound check elimination
A flaw was found in the cmd/compile package in the Go standard library. The compiler fails to correctly check for integer overflow or underflow in arithmetic operations involving loop induction variables. As a result, the compiler allows invalid memory indexing to occur at runtime, potentially...
crypto/x509: golang: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries
A flaw was found in the crypto/x509 package of golang. This vulnerability allows a remote attacker to cause a Denial of Service DoS by presenting a specially crafted X.509 certificate with a large number of DNS Subject Alternative Name SAN entries. The certificate verification process, specifical...
crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building
A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...
crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation
A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...
crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages
A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...
encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal
A flaw was found in the encoding/asn1 package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One ASN.1 structure, leading to excessive recursion during the Unmarshal operation. This could result in stack exhaustion and a Denial of Service DoS conditio...
