Full Disclosure is a "lightly moderated" security mailing list generally used for discussion about information security and disclosure of vulnerabilities. The list was created on July 9, 2002, by Len Rose and also administered by him, who later handed it off to John Cartwright.
He is known for discovering a large number of security vulnerabilities in Apple products, including iOS, [1] Safari [3] and macOS, [4] as well as helping create jailbreaks for iOS versions. [ 5 ] [ 6 ] One such discovery forced Apple to rewrite significant parts of the macOS and iOS kernel . [ 7 ]
It was a high-volume mailing list, with as many as 776 posts in a month, [1] and almost all new security vulnerabilities were discussed on the list in its early days. The forum provided a vehicle for anyone to disclose and discuss computer vulnerabilities , including security researchers and product vendors.
The vulnerabilities are a mixture of information leak vulnerabilities, remote code execution vulnerability or logical flaw vulnerabilities. The Apple iOS vulnerability was a remote code execution vulnerability due to the implementation of LEAP (Low Energy Audio Protocol). This vulnerability was only present in older versions of the Apple iOS. [17]
Step 3 – The scanner checks for vulnerabilities. Step 4 – When vulnerabilities are detected, the results are categorized in several ways, allowing customers to target the data they find most useful. SAINT can group vulnerabilities according to severity, type, or count. It can also provide information about a particular host or group of hosts.
Security Administrator Tool for Analyzing Networks (SATAN) was a free software vulnerability scanner for analyzing networked computers.SATAN captured the attention of a broad technical audience, appearing in PC Magazine [1] and drawing threats from the United States Department of Justice. [1]
The solution eliminates all unaligned free-branch instructions (instructions like RET or CALL which attackers can use to change control flow) inside a binary executable, and protects the free-branch instructions from being used by an attacker. The way G-Free protects the return address is similar to the XOR canary implemented by StackGuard ...
