Details of six flaws in Mozilla, the open source browser were posted on BugTraq at the weekend. Versions of Mozilla previous to version 1.0.1 contain multiple security vulnerabilities, so users need to update their browser software. The flaws could be used by an attacker to read data off of the local hard drive, gain information which should normally be kept private, and in some cases to execute arbitrary code, an advisory by Red Hat explains.
That advisory was published on October 18, and dealt with problems that first came to light in September. Last Friday (November 1) BugTraq posted a half dozen updated advisories which spell out the various risks and gives links to proof on concept demonstrations relating to the six.
Firstly, and most seriously, we touch on a well reported weakness in Mozilla which meand that surfers may not get sufficient warning when being redirected from secure sites to other secure sites via non-secure sites. The consequences of this HTTP/HTTPS Redirection Weakness for ecommerce are serious and at very least may give users a false sense of security when browsing the Internet.
