Dec 13, 2010I know, it's really weird.Chromium version 8.0.552.215 in Ubuntu 10.10 is thinking that PDF files are dangerous.
Code:
This type of file may harm your computer. Download anyway? (Yes/No)I don't need this fixed immediately, as it is only a minor annoyance.
I know my sources of the PDF's so I know that they don't have any malware attached.
Networking :: Using ESTABLISHED And RELATED Together Seems Dangerous
Apr 16, 2011I've seen packets coming to my computer through a DD-WRTv24s2 gateway above port 32K several times. I have iptables (using fwbuilder locally) both places. My desktop stops the packets. But I'm guessing the problem is as I described in the title for this post. Yes?If you ESTABLISH a connection to some webpage, and you just accept ESTABLISHED or RELATED datagrams in rule 1 of your iptables, what will keep incoming TCP from that (presumably nefarious) site from going straight to your desktop like the building firewall isn't there?? If the site wants to connect to you above 32k, or portscan you, its RELATED correct? They know your IP. You've ESTABLISHED a connection.If my guess is correct, it would seem wiser to NEVER use these together. Better to ACCEPT all ESTABLISHED. And if something is RELATED, then ACCEPT it only if its the data connection on FTP or individually by service or protocol.

View 1 Replies View RelatedSecurity :: 2010 CWE/SANS Top 25 Most Dangerous Programming Errors
Apr 7, 2010The 2010 CWE/SANS Top 25 Most Dangerous Programming Errors is a list of the most widespread and critical programming errors that can lead to serious software vulnerabilities. They are often easy to find, and easy to exploit. They are dangerous because they will frequently allow attackers to completely take over the software, steal data, or prevent the software from working at all.
The Top 25 list is a tool for education and awareness to help programmers to prevent the kinds of vulnerabilities that plague the software industry, by identifying and avoiding all-too-common mistakes that occur before software is even shipped. Software customers can use the same list to help them to ask for more secure software. Researchers in software security can use the Top 25 to focus on a narrow but important subset of all known security weaknesses. Finally, software managers and CIOs can use the Top 25 list as a measuring stick of progress in their efforts to secure their software.

32
