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...

html/template: golang: Go html/template: Cross-Site Scripting via improper URL escaping in meta tag content

A flaw was found in the html/template package of Go. A remote attacker could exploit this vulnerability by inserting ASCII whitespaces around the equals sign = within a URL's content attribute inside a tag. This improper escaping could lead to Cross-Site Scripting XSS, allowing the attacker to...

net/http/httputil: golang: net/http/httputil: ReverseProxy forwards hidden query parameters, potentially bypassing security controls

A flaw was found in the net/http/httputil package, specifically within the ReverseProxy component. This vulnerability allows the ReverseProxy to forward query parameters that are not visible to Rewrite functions. This occurs because the ReverseProxy does not correctly consider the url.ParseQuery...

html/template: golang: html/template: Cross-site scripting due to incorrect script tag escaping

A flaw was found in html/template. A trusted template author could craft a script tag with an empty or whitespace-only 'type' attribute. This vulnerability causes the template engine to incorrectly escape data passed into the script block, potentially leading to cross-site scripting XSS. An...

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: Go os.Root: Symlink following vulnerability allows directory traversal

A flaw was found in the os.Root functionality of Go on Unix systems. This vulnerability allows an attacker to bypass intended directory restrictions by crafting a path that ends with a symbolic link and a trailing slash. When a file is opened in os.Root with such a path, the symbolic link is...

cmd/go: golang: Go command (cmd/go): Integrity bypass due to checksum validation flaw via malicious module proxy

A flaw was found in the Go command cmd/go. A malicious module proxy can exploit this vulnerability by bypassing the validation of module checksums. This allows the proxy to serve altered versions of the Go toolchain, which the go command may then download and execute without proper verification...
