Debian Linux Security Advisory 5480-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

New research reveals the strategies hackers use to hide their malware distribution system, and companies are rushing to release mitigations for the “Downfall” processor vulnerability on Intel chips.

Improper path handling in Typora before 1.6.7 on Windows and Linux allows a crafted webpage to access local files and exfiltrate them to remote web servers via "typora://app/<absolute-path>". This vulnerability can be exploited if a user opens a malicious markdown file in Typora, or copies text from a malicious webpage and paste it into Typora.

Improper path handling in Typora before 1.7.0-dev on Windows and Linux allows a crafted webpage to access local files and exfiltrate them to remote web servers via "typora://app/typemark/". This vulnerability can be exploited if a user opens a malicious markdown file in Typora, or copies text from a malicious webpage and paste it into Typora.

Improper path handling in Obsidian desktop before 1.2.8 on Windows, Linux and macOS allows a crafted webpage to access local files and exfiltrate them to remote web servers via "app://local/<absolute-path>". This vulnerability can be exploited if a user opens a malicious markdown file in Obsidian, or copies text from a malicious webpage and paste it into Obsidian.

DOM-based XSS in src/muya/lib/contentState/pasteCtrl.js in MarkText 0.17.1 and before on Windows, Linux and macOS allows arbitrary JavaScript code to run in the context of MarkText main window. This vulnerability can be exploited if a user copies text from a malicious webpage and paste it into MarkText.

DOM-based XSS in updater/update.html in Typora before 1.6.7 on Windows and Linux allows a crafted markdown file to run arbitrary JavaScript code in the context of Typora main window via loading typora://app/typemark/updater/update.html in <embed> tag. This vulnerability can be exploited if a user opens a malicious markdown file in Typora, or copies text from a malicious webpage and paste it into Typora.

Apache NiFi 1.21.0 through 1.23.0 support JDBC and JNDI JMS access in several Processors and Controller Services with connection URL validation that does not provide sufficient protection against crafted inputs. An authenticated and authorized user can bypass connection URL validation using custom input formatting. The resolution enhances connection URL validation and introduces validation for additional related properties. Upgrading to Apache NiFi 1.23.1 is the recommended mitigation.

Online Shopping Portal Project 3.1 allows remote attackers to execute arbitrary SQL commands/queries via the login form, leading to unauthorized access and potential data manipulation. This vulnerability arises due to insufficient validation of user-supplied input in the username field, enabling SQL Injection attacks.

Cisco ThousandEyes Enterprise Agent Virtual Appliance version thousandeyes-va-64-18.04 0.218 suffers from an unpatched vulnerability in sudoedit, allowed by sudo configuration, which permits a low-privilege user to modify arbitrary files as root and subsequently execute arbitrary commands as root.
