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...

go-git's improper parsing of specially crafted objects may lead to inconsistent interpretation compared to upstream Git

Impact go-git may parse malformed Git objects in a way that differs from upstream Git. When commit or tag objects contain ambiguous or malformed headers, go-git’s decoded representation may expose values differently from how Git itself would interpret or reject the same object. Additionally,...

github.com/sirupsen/logrus: github.com/sirupsen/logrus: Denial-of-Service due to large single-line payload

A denial-of-service vulnerability in github.com/sirupsen/logrus occurs when Entry.Writer processes a single-line payload larger than 64KB with no newline characters. Due to a limitation in Go’s internal bufio.Scanner, the read operation fails with a “token too long” error, causing the underlying...

BIT-GOLANG-2026-39819 Invoking "go bug" follows symlinks in predictable temporary filenames in cmd/go

The "go bug" command writes to two files with predictable names in the system temporary directory for example, "/tmp". An attacker with access to the temporary directory can create a symlink in one of these names, causing "go bug" to overwrite the target of the symlink...

BIT-GOLANG-2026-39817 Invoking "go tool pack" does not sanitize output paths in cmd/go

The "go tool pack" subcommand usually used only by the compiler as an internal tool with known-good inputs does not sanitize output filenames. Extracting a malicious archive file with the "pack" subcommand can write files to arbitrary locations on the filesystem...
