Ubuntu 5.04 : mozilla-firefox, mozilla vulnerabilities (USN-124-1)
High Nessus Plugin ID 20513
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionWhen a popup is blocked the user is given the ability to open that popup through the popup-blocking status bar icon and, in Firefox, through the information bar. Doron Rosenberg noticed that popups which are permitted by the user were executed with elevated privileges, which could be abused to automatically install and execute arbitrary code with the privileges of the user. (CAN-2005-1153)
Michael Krax found two flaws in the Search Plugin installation. This allowed malicious plugins to execute arbitrary code in the context of the current site. If the current page had elevated privileges (like 'about:plugins' or 'about:config'), the malicious plugin could even install malicious software when a search was performed.
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.
SolutionUpdate the affected packages.
