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...

Security update for the Linux Kernel (Live Patch 32 for SUSE Linux Enterprise 15 SP5)

This update for the SUSE Linux Enterprise Kernel 5.14.21-150500.55.127 fixes various security issues: The following security issues were fixed: CVE-2026-46150: fanotify: fix false positive on permission events bsc1267388.

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...

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/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: 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/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...
