openSUSE Security Update : mozilla-js192 (mozilla-js192-4105)
Critical Nessus Plugin ID 75954
SynopsisThe remote openSUSE host is missing a security update.
DescriptionMozillaFirefox was updated to version 188.8.131.52, fixing various security issues.
Following security issues were fixed: MFSA 2011-01: Mozilla developers identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code. References
Jesse Ruderman, Igor Bukanov, Olli Pettay, Gary Kwong, Jeff Walden, Henry Sivonen, Martijn Wargers, David Baron and Marcia Knous reported memory safety problems that affected Firefox 3.6 and Firefox 3.5.
Igor Bukanov and Gary Kwong reported memory safety problems that affected Firefox 3.6 only. (CVE-2011-0062)
MFSA 2011-02 / CVE-2011-0051: Security researcher Zach Hoffman reported that a recursive call to eval() wrapped in a try/catch statement places the browser into a inconsistent state. Any dialog box opened in this state is displayed without text and with non-functioning buttons. Closing the window causes the dialog to evaluate to true. An attacker could use this issue to force a user into accepting any dialog, such as one granting elevated privileges to the page presenting the dialog.
MFSA 2011-03 / CVE-2011-0055: Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that a method used by JSON.stringify contained a use-after-free error in which a currently in-use pointer was freed and subsequently dereferenced. This could lead to arbitrary code execution if an attacker was able to store malicious code in the freed section of memory.
Mozilla developer Igor Bukanov also independently discovered and reported this issue two weeks after the initial report was received.
MFSA 2011-07 / CVE-2011-0058: Alex Miller reported that when very long strings were constructed and inserted into an HTML document, the browser would incorrectly construct the layout objects used to display the text. Under such conditions an incorrect length would be calculated for a text run resulting in too small of a memory buffer being allocated to store the text. This issue could be used by an attacker to write data past the end of the buffer and execute malicious code on a victim's computer. This issue affects only Mozilla browsers on Windows.
While there are no unsafe uses of this class in any released products, extension code could have potentially used it in an unsafe manner.
MFSA 2011-09 / CVE-2011-0061: Security researcher Jordi Chancel reported that a JPEG image could be constructed that would be decoded incorrectly, causing data to be written past the end of a buffer created to store the image. An attacker could potentially craft such an image that would cause malicious code to be stored in memory and then later executed on a victim's computer.
MFSA 2011-10 / CVE-2011-0059: Adobe security researcher Peleus Uhley reported that when plugin-initiated requests receive a 307 redirect response, the plugin is not notified and the request is forwarded to the new location. This is true even for cross-site redirects, so any custom headers that were added as part of the initial request would be forwarded intact across origins. This poses a CSRF risk for web applications that rely on custom headers only being present in requests from their own origin.
