OpenTelemetry-Go is the Go implementation of OpenTelemetry.

The tar extraction routines in moby/go-archive (Unpack, UnpackLayer, Untar/UntarUncompressed, and the ApplyLayer helpers) do not confine filesystem operations to the destination directory.

OpenTelemetry-Go is the Go implementation of OpenTelemetry.

Previously, a revoked 'SignatureKey' belonging to a CA was not correctly checked for revocation.

Previously, CVE-2024-45337 fixed an authorization bypass for misused ssh server configurations; if any other type of callback is passed other than public key, then the source-address validation would be skipped.

When adding a key to a remote agent constraint extensions such as [email protected] were not serialized in the request.

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

A malicious SSH peer could send unsolicited global request responses to fill an internal buffer, blocking the connection's read loop.

spdystream is a Go library for multiplexing streams over SPDY connections.

Uncontrolled recursion in the unknown-key skip path of the aws-smithy-json runtime crate before 0.62.7, which the smithy-rs code generator invokes from every generated struct deserializer, might allow remote unauthentica…

BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and repeatable manner.

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.

The TIFF decoder can panic when decoding an invalid image with an out-of-bounds strip offset.

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.

When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a sec…

A malicious BuildKit client or frontend could craft a request that could lead to BuildKit daemon crashing with a panic.

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.

SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate.
