dp-golang is a Puppet module for Go installations. Prior to 1.2.7, dp-golang could install files — including the compiler binary — with the wrong ownership when Puppet was run as root and the installed package was On macOS: Go version 1.4.3 through 1.21rc3, inclusive, go1.4-bootstrap-20170518.tar.gz, or go1.4-bootstrap-20170531.tar.gz. The user and group specified in Puppet code were ignored for files within the archive. dp-puppet version 1.2.7 will recreate installations if the owner or group of any file or directory within that installation does not match the requested owner or group

When logs are written to a widely-writable directory (the default), an unprivileged attacker may predict a privileged process's log file path and pre-create a symbolic link to a sensitive file in its place. When that privileged process runs, it will follow the planted symlink and overwrite that sensitive file. To fix that, glog now causes the program to exit (with status code 2) when it finds that the configured log file already exists.

An attacker can craft an input to the Parse functions that would be processed non-linearly with respect to its length, resulting in extremely slow parsing. This could cause a denial of service.

Applications and libraries which misuse connection.serverAuthenticate (via callback field ServerConfig.PublicKeyCallback) may be susceptible to an authorization bypass. The documentation for ServerConfig.PublicKeyCallback says that "A call to this function does not guarantee that the key offered is in fact used to authenticate." Specifically, the SSH protocol allows clients to inquire about whether a public key is acceptable before proving control of the corresponding private key. PublicKeyCallback may be called with multiple keys, and the order in which the keys were provided cannot be used to infer which key the client successfully authenticated with, if any. Some applications, which store the key(s) passed to PublicKeyCallback (or derived information) and make security relevant determinations based on it once the connection is established, may make incorrect assumptions. For example, an attacker may send public keys A and B, and then authenticate with A. PublicKeyCallback would be …

A vulnerability was found in Gouniverse GoLang CMS 1.4.0. It has been declared as problematic. This vulnerability affects the function PageRenderHtmlByAlias of the file FrontendHandler.go. The manipulation of the argument alias leads to cross site scripting. The attack can be initiated remotely. Upgrading to version 1.4.1 is able to address this issue. The patch is identified as 3e661cdfb4beeb9fe2ad507cdb8104c0b17d072c. It is recommended to upgrade the affected component.

httpTokenCacheKey uses path.Base to extract the expected HTTP-01 token value to lookup in the DirCache implementation. On Windows, path.Base acts differently to filepath.Base, since Windows uses a different path separator (\ vs. /), allowing a user to provide a relative path, i.e. .well-known/acme-challenge/..\..\asd becomes ..\..\asd. The extracted path is then suffixed with +http-01, joined with the cache directory, and opened. Since the controlled path is suffixed with +http-01 before opening, the impact of this is significantly limited, since it only allows reading arbitrary files on the system if and only if they have this suffix.

Parsing a corrupt or malicious image with invalid color indices can cause a panic.

A command inject vulnerability allows an attacker to perform command injection on Windows applications that indirectly depend on the CreateProcess function when the specific conditions are satisfied.

An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection.

The protojson.Unmarshal function can enter an infinite loop when unmarshaling certain forms of invalid JSON. This condition can occur when unmarshaling into a message which contains a google.protobuf.Any value, or when the UnmarshalOptions.DiscardUnknown option is set.
