Gallagher Controller 6000 is vulnerable to a Denial of Service attack via conflicting ARP packets with a duplicate IP address. This issue affects: Gallagher Gallagher Controller 6000 vCR8.60 versions prior to 220303a; vCR8.50 versions prior to 220303a; vCR8.40 versions prior to 220303a; vCR8.30 versions prior to 220303a.

Red Hat Security Advisory 2022-5498-01 - Red Hat Satellite is a systems management tool for Linux-based infrastructure. It allows for provisioning, remote management, and monitoring of multiple Linux deployments with a single centralized tool. Issues addressed include HTTP request smuggling, buffer overflow, bypass, code execution, cross site scripting, denial of service, heap overflow, information leakage, privilege escalation, remote shell upload, remote SQL injection, and traversal vulnerabilities.

In audio DSP, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS06558844; Issue ID: ALPS06558844.

** DISPUTED ** quic-go through 0.27.0 allows remote attackers to cause a denial of service (CPU consumption) via a Slowloris variant in which incomplete QUIC or HTTP/3 requests are sent. This occurs because mtu_discoverer.go misparses the MTU Discovery service and consequently overflows the probe timer. NOTE: the vendor's position is that this behavior should not be listed as a vulnerability on the CVE List.

NULL Pointer Dereference allows attackers to cause a denial of service (or application crash). This only applies when lxml is used together with libxml2 2.9.10 through 2.9.14. libxml2 2.9.9 and earlier are not affected. It allows triggering crashes through forged input data, given a vulnerable code sequence in the application. The vulnerability is caused by the iterwalk function (also used by the canonicalize function). Such code shouldn't be in wide-spread use, given that parsing + iterwalk would usually be replaced with the more efficient iterparse function. However, an XML converter that serialises to C14N would also be vulnerable, for example, and there are legitimate use cases for this code sequence. If untrusted input is received (also remotely) and processed via iterwalk function, a crash can be triggered.

**Summary** The issue is the same as CVE-2021-43306: An exponential ReDoS (Regular Expression Denial of Service) can be triggered in the jquery-validation npm package, when an attacker is able to supply arbitrary input to the url2 method The fix for CVE-2021-43306, which was suggested by me ([@erik-krogh](https://github.com/erik-krogh)), was incomplete. I didn't know at the time that the fix was incomplete, but the ReDoS analysis in CodeQL has improved since then. **Details** Issue: ReDoS in url2.js (GHSL-2022-039) Below is a PoC that contains the relevant regular expression. Run following script with node and you will notice that it doesn't terminate. ```js const reg = /^(?:(?:(?:https?|ftp):)?\/\/)(?:\S+(?::\S*)?@)?(?:(?!(?:10|127)(?:\.\d{1,3}){3})(?!(?:169\.254|192\.168)(?:\.\d{1,3}){2})(?!172\.(?:1[6-9]|2\d|3[0-1])(?:\.\d{1,3}){2})(?:[1-9]\d?|1\d\d|2[01]\d|22[0-3])(?:\.(?:1?\d{1,2}|2[0-4]\d|25[0-5])){2}(?:\.(?:[1-9]\d?|1\d\d|2[0-4]\d|25[0-4]))|(?:(?:[a-z0-9\u00a1-\uffff][a-z0-...

The heap buffer-overflow issue in Chrome for Android could be used for DoS, code execution, and more.

IBM App Connect Enterprise Certified Container 4.2 could allow a user from the administration console to cause a denial of service by creating a specially crafted request. IBM X-Force ID: 228221.
