Ubuntu Security Notice 6574-1 - Takeshi Kaneko discovered that Go did not properly handle comments and special tags in the script context of html/template module. An attacker could possibly use this issue to inject Javascript code and perform a cross site scripting attack. This issue only affected Go 1.20 in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and Ubuntu 23.04. It was discovered that Go did not properly validate the "//go:cgo_" directives during compilation. An attacker could possibly use this issue to inject arbitrary code during compile time.

A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response body to read many more bytes from the network than are in the body. A malicious HTTP client can further exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a handler fails to read the entire body of a request. Chunk extensions are a little-used HTTP feature which permit including additional metadata in a request or response body sent using the chunked encoding. The net/http chunked encoding reader discards this metadata. A sender can exploit this by inserting a large metadata segment with each byte transferred. The chunk reader now produces an error if the ratio of real body to encoded bytes grows too small.

Using go get to fetch a module with the ".git" suffix may unexpectedly fallback to the insecure "git://" protocol if the module is unavailable via the secure "https://" and "git+ssh://" protocols, even if GOINSECURE is not set for said module. This only affects users who are not using the module proxy and are fetching modules directly (i.e. GOPROXY=off).

Red Hat Security Advisory 2023-7653-03 - An update to the images for Red Hat Integration - Service Registry is now available from the Red Hat Container Catalog. The purpose of this text-only errata is to inform you about the security issues fixed in this release. Issues addressed include bypass and denial of service vulnerabilities.

Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS#1 padding may leak timing information, which in turn could be used to recover session key bits. In Go 1.20, the crypto/tls library switched to a fully constant time RSA implementation, which we do not believe exhibits any timing side channels.

Hello everyone! October was an interesting and busy month for me. I started a new job, worked on my open source Vulristics project, and analyzed vulnerabilities using it. Especially Linux vulnerabilities as part of my new Linux Patch Wednesday project. And, of course, analyzed Microsoft Patch Tuesday as well. In addition, at the end of […]

Debian Linux Security Advisory 5540-1 - Two remotely exploitable security vulnerabilities were discovered in Jetty 9, a Java based web server and servlet engine. The HTTP/2 protocol implementation did not sufficiently verify if HPACK header values exceed their size limit. Furthermore the HTTP/2 protocol allowed a denial of service (server resource consumption) because request cancellation can reset many streams quickly. This problem is also known as Rapid Reset Attack.

Ubuntu Security Notice 6438-1 - Kevin Jones discovered that .NET did not properly process certain X.509 certificates. An attacker could possibly use this issue to cause a denial of service. It was discovered that the .NET Kestrel web server did not properly handle HTTP/2 requests. A remote attacker could possibly use this issue to cause a denial of service.

Red Hat Security Advisory 2023-5713-01 - nginx is a web and proxy server supporting HTTP and other protocols, with a focus on high concurrency, performance, and low memory usage. Issues addressed include a denial of service vulnerability.

A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2 for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see ...
