A flaw was found in the Linux kernel’s networking code. A use-after-free was found in the way the sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed) into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a denial of service.

jsonlint 1.0 is vulnerable to heap-buffer-overflow via /home/hjsz/jsonlint/src/lexer.

Relatedcode's Messenger version 7bcd20b allows an authenticated external attacker to access sensitive data of any user of the application. This is possible because the application exposes user data to the public.

Markdownify version 1.4.1 allows an external attacker to execute arbitrary code remotely on any client attempting to view a malicious markdown file through Markdownify. This is possible because the application has the "nodeIntegration" option enabled.

We need more than the incomplete snapshot SBOMs provide to have real impact.

A cross-site request forgery (CSRF) vulnerability in Jenkins Katalon Plugin 1.0.33 and earlier allows attackers to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

Former chair bemoans ‘coup by governance’

This Metasploit module exploits an authentication bypass vulnerability in the Fortinet FortiOS, FortiProxy, and FortiSwitchManager API to gain access to a chosen account and then adds an SSH key to the authorized_keys file of the chosen account, allowing you to login to the system with the chosen account. Successful exploitation results in remote code execution.

This Metasploit module exploits a vulnerable sudo configuration that permits the Zimbra user to execute postfix as root. In turn, postfix can execute arbitrary shellscripts, which means it can execute a root shell.

Debian Linux Security Advisory 5258-1 - Several vulnerabilities were discovered in Squid, a fully featured web proxy cache, which could result in exposure of sensitive information in the cache manager (CVE-2022-41317), or denial of service or information disclosure if Squid is configured to negotiate authentication with the SSPI and SMB authentication helpers (CVE-2022-41318).
