Improper sanitization of the value of the `[srcset]` attribute in `<source>` HTML elements in AngularJS allows attackers to bypass common image source restrictions, which can also lead to a form of Content Spoofing https://owasp.org/www-community/attacks/Content_Spoofing . This issue affects all versions of AngularJS. Note: The AngularJS project is End-of-Life and will not receive any updates to address this issue.

Stegano is a basic Python Steganography module. Stegano implements two methods of hiding: using the red portion of a pixel to hide ASCII messages, and using the Least Significant Bit (LSB) technique. It is possible to use a more advanced LSB method based on integers sets. The sets (Sieve of Eratosthenes, Fermat, Carmichael numbers, etc.) are used to select the pixels used to hide the information.
PacketFence is a network access control (NAC) system. It is actively maintained and has been deployed in numerous large-scale institutions. It can be used to effectively secure networks, from small to very large heterogeneous networks. PacketFence provides NAC-oriented features such as registration of new network devices, detection of abnormal network activities including from remote snort sensors, isolation of problematic devices, remediation through a captive portal, and registration-based and scheduled vulnerability scans.
Ubuntu Security Notice 6995-1 - Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. It was discovered that Thunderbird did not properly manage certain memory operations when processing graphics shared memory. An attacker could potentially exploit this issue to escape the sandbox.
By having specific DDL permissions set in Oracle 19c, you can bypass access restrictions normally in place for VPD (virtual private database).
