Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Gary Kwong, Igor Bukanov, and Bob Clary discovered multiple memory vulnerabilities in the browser rendering engine. An attacker could use these to possibly execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2982)

It was discovered that a vulnerability in event management code could permit JavaScript to be run in the wrong context. This could potentially allow a malicious website to run code as another website or with escalated privileges within the browser. (CVE-2011-2981)

It was discovered that an SVG text manipulation routine contained a dangling pointer vulnerability. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-0084)

It was discovered that web content could receive chrome privileges if it registered for drop events and a browser tab element was dropped into the content area. This could potentially allow a malicious website to run code with escalated privileges within the browser.
(CVE-2011-2984)

It was discovered that appendChild contained a dangling pointer vulnerability. An attacker could potentially use this to crash Firefox or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2378)

It was discovered that data from other domains could be read when RegExp.input was set. This could potentially allow a malicious website access to private data from other domains. (CVE-2011-2983).

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.
