Ubuntu 8.04 LTS : firefox-3.0, xulrunner-1.9 regression (USN-645-3)
Critical Nessus Plugin ID 38073
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionUSN-645-1 fixed vulnerabilities in Firefox and xulrunner. The upstream patches introduced a regression in the saved password handling. While password data was not lost, if a user had saved any passwords with non-ASCII characters, Firefox could not access the password database.
This update fixes the problem.
We apologize for the inconvenience.
Justin Schuh, Tom Cross and Peter Williams discovered errors in the Firefox URL parsing routines. If a user were tricked into opening a crafted hyperlink, an attacker could overflow a stack buffer and execute arbitrary code. (CVE-2008-0016)
This could allow an attacker to execute scripts from page content with chrome privileges. (CVE-2008-3836)
Paul Nickerson discovered Firefox did not properly process mouse click events. If a user were tricked into opening a malicious web page, an attacker could move the content window, which could potentially be used to force a user to perform unintended drag and drop operations. (CVE-2008-3837)
Several problems were discovered in the browser engine. This could allow an attacker to execute code with chrome privileges. (CVE-2008-4058, CVE-2008-4059, CVE-2008-4060)
Drew Yao, David Maciejak and other Mozilla developers found several problems in the browser engine of Firefox. If a user were tricked into opening a malicious web page, an attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-4061, CVE-2008-4062, CVE-2008-4063, CVE-2008-4064)
Gareth Heyes discovered a flaw in the HTML parser of Firefox. If a user were tricked into opening a malicious web page, an attacker could bypass script filtering and perform cross-site scripting attacks. (CVE-2008-4066)
Boris Zbarsky and Georgi Guninski independently discovered flaws in the resource: protocol. An attacker could exploit this to perform directory traversal, read information about the system, and prompt the user to save information in a file. (CVE-2008-4067, CVE-2008-4068)
Billy Hoffman discovered a problem in the XBM decoder. If a user were tricked into opening a malicious web page or XBM file, an attacker may be able to cause a denial of service via application crash. (CVE-2008-4069).
