Cyber Security Bulletin 2005 Summary
2005 Year-End Index

Information in the US-CERT Cyber Security Bulletin is a compilation and includes
information published by outside sources, so the information should not
be considered the result of US-CERT analysis. Software vulnerabilities
are categorized in the appropriate section reflecting the operating
system on which the vulnerability was reported; however, this does not
mean that the vulnerability only affects the operating system reported
since this information is obtained from open-source information.

This bulletin provides a year-end summary of software vulnerabilities that
were identified between January 2005 and December 2005. The information
is presented only as a index with links to the US-CERT Cyber Security
Bulletin the information was published in. There were 5198 reported
vulnerabilities: 812 Windows operating system vulnerabilities; 2328
Unix/Linux operating vulnerabilities; and 2058 Multiple operating
system vulnerabilities.
