SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionAlexey Proskuryakov, Yosuke Hasegawa and Simon Montagu discovered flaws in Firefox's character encoding handling. If a user were tricked into opening a malicious web page, an attacker could perform cross-site scripting attacks. (CVE-2008-0416)
(CVE-2008-1233, CVE-2008-1234, CVE-2008-1235)
Several problems were discovered in Firefox which could lead to crashes and memory corruption. If a user were tricked into opening a malicious web page, an attacker may be able to execute arbitrary code with the user's privileges. (CVE-2008-1236, CVE-2008-1237)
Gregory Fleischer discovered Firefox did not properly process HTTP Referrer headers when they were sent with with requests to URLs containing Basic Authentication credentials with empty usernames. An attacker could exploit this vulnerability to perform cross-site request forgery attacks. (CVE-2008-1238)
Peter Brodersen and Alexander Klink reported that default the setting in Firefox for SSL Client Authentication allowed for users to be tracked via their client certificate. The default has been changed to prompt the user each time a website requests a client certificate.
Gregory Fleischer discovered that web content fetched via the jar protocol could use Java LiveConnect to connect to arbitrary ports on the user's machine due to improper parsing in the Java plugin. If a user were tricked into opening malicious web content, an attacker may be able to access services running on the user's machine.
Chris Thomas discovered that Firefox would allow an XUL popup from an unselected tab to display in front of the selected tab. An attacker could exploit this behavior to spoof a login prompt and steal the user's credentials. (CVE-2008-1241).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
