OpenTelemetry-Go is the Go implementation of OpenTelemetry.

PostCSS takes a CSS file and provides an API to analyze and modify its rules by transforming the rules into an Abstract Syntax Tree.

The Verify() method for FIDO/U2F security key types ([email protected], [email protected]) did not check the User Presence flag.

Arc is an open, SQL-native time-series database for telemetry.

When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint.

Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not.

Previously, DecodeElement would reset the depth counter causing it to never fire; this could lead to stack exhaustion.

When a server is configured to support unencrypted HTTP/2, it reads a few bytes from each new connection to see if they contain the HTTP/2 client preface.

Decoding a maliciously-crafted MIME header containing many invalid encoded-words can consume excessive CPU.

Pathological inputs could cause DoS through consumePhrase when parsing an email address according to RFC 5322.

Well-crafted inputs reaching ParseAddress, ParseAddressList, and ParseDate were able to trigger excessive CPU exhaustion and memory allocations.

Enforce a recursion limit in Unmarshal to prevent stack exhaustion when parsing deeply-nested, recursive structures.

A norm.Iter can enter an infinite loop when handling input containing invalid UTF-8 bytes.

An incorrectly placed cast from bytes to int allowed for server-side panic in the AES-GCM packet decoder for well-crafted inputs.

The MongoDB Go Driver's client-level bulk write operation may accept a caller-supplied database name containing a reserved separator character without escaping it before the name is used to build the target namespace for…

Moby is an open source container framework.

(*x509.Certificate).VerifyHostname previously called matchHostnames in a loop over all DNS Subject Alternative Name (SAN) entries.

Billy is an interface filesystem abstraction for Go.

Previously, resolving relative paths containing parent directory ('..') segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead.

Previously, pathological inputs could close an unescaped '/' early, allowing for attack-controlled data to inject arbitrary content, potentially leading to XSS.
