Red Hat Security Advisory 2023-0189-01 - Red Hat AMQ Streams, based on the Apache Kafka project, offers a distributed backbone that allows microservices and other applications to share data with extremely high throughput and extremely low latency. This release of Red Hat AMQ Streams 2.3.0 serves as a replacement for Red Hat AMQ Streams 2.2.0, and includes security and bug fixes, and enhancements. Issues addressed include a denial of service vulnerability.

The maintainers of the Git source code version control system have released updates to remediate two critical vulnerabilities that could be exploited by a malicious actor to achieve remote code execution. The flaws, tracked as CVE-2022-23521 and CVE-2022-41903, impacts the following versions of Git: v2.30.6, v2.31.5, v2.32.4, v2.33.5, v2.34.5, v2.35.5, v2.36.3, v2.37.4, v2.38.2, and v2.39.0.

Versions of the package cookiejar before 2.1.4 are vulnerable to Regular Expression Denial of Service (ReDoS) via the `Cookie.parse` function and other aspects of the API, which use an insecure regular expression for parsing cookie values. Applications could be stalled for extended periods of time if untrusted input is passed to cookie values or attempted to parse from request headers. Proof of concept: ``` ts\nconst { CookieJar } = require("cookiejar"); const jar = new CookieJar(); const start = performance.now(); const attack = "a" + "t".repeat(50_000); jar.setCookie(attack); console.log(`CookieJar.setCookie(): ${performance.now() - start}ms`); ``` ``` CookieJar.setCookie(): 2963.214399999939ms ```

Versions of the package cookiejar before 2.1.4 are vulnerable to Regular Expression Denial of Service (ReDoS) via the Cookie.parse function, which uses an insecure regular expression.

Sewio’s Real-Time Location System (RTLS) Studio version 2.0.0 up to and including version 2.6.2 is vulnerable to cross-site request forgery in its backup services. An attacker could take advantage of this vulnerability to execute arbitrary backup operations and cause a denial-of-service condition.

mechanize, a library for automatically interacting with HTTP web servers, contains a regular expression that is vulnerable to regular expression denial of service (ReDoS) prior to version 0.4.6. If a web server responds in a malicious way, then mechanize could crash. Version 0.4.6 has a patch for the issue.

In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control configuration that is set up with "tc qdisc" and "tc class" commands. This affects qdisc_graft in net/sched/sch_api.c.

A NULL pointer dereference vulnerability in the Linux kernel NVMe functionality, in nvmet_setup_auth(), allows an attacker to perform a Pre-Auth Denial of Service (DoS) attack on a remote machine. Affected versions v6.0-rc1 to v6.0-rc3, fixed in v6.0-rc4.
