SuSE 11.1 Security Update : Mozillla Firefox (SAT Patch Number 4104)

Critical Nessus Plugin ID 52650


The remote SuSE 11 host is missing one or more security updates.


Mozilla Firefox has been updated to version 3.6.15, fixing the following security issues :

- Several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products have been identified and fixed. Some of these bugs showed evidence of memory corruption under certain circumstances, and it is assumed that with enough effort at least some of these could be exploited to run arbitrary code. (MFSA 2011-01 / CVE-2011-0053 / CVE-2011-0062)

- 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 2011-02 / CVE-2011-0051)

- A method used by JSON.stringify contains 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 is able to store malicious code in the freed section of memory.
(MFSA 2011-03 / CVE-2011-0055)

- The JavaScript engine's internal memory mapping of non-local JS variables contains a buffer overflow which could potentially be used by an attacker to run arbitrary code on a victim's computer. (MFSA 2011-04 / CVE-2011-0054)

- The JavaScript engine's internal mapping of string values contains an error in cases where the number of values being stored is above 64K. In such cases an offset pointer is manually moved forwards and backwards to access the larger address space. If an exception is thrown between the time that the offset pointer was moved forward and the time it gets reset, the exception object would be read from an invalid memory address, potentially executing attacker-controlled memory. (MFSA 2011-05 / CVE-2011-0056)

- A JavaScript Worker could be used to keep a reference to an object that could be freed during garbage collection.
Subsequent calls through this deleted reference could cause attacker-controlled memory to be executed on a victim's computer. (MFSA 2011-06 / CVE-2011-0057)

- When very long strings are constructed and inserted into an HTML document, the browser incorrectly constructs 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. It affects only Mozilla browsers on Windows. (MFSA 2011-07 / CVE-2011-0058)

- ParanoidFragmentSink, a class used to sanitize potentially unsafe HTML for display, allows javascript:
URLs and other inline JavaScript when the embedding document is a chrome document. While there are no unsafe uses of this class in any released products, extension code could potentially use it in an unsafe manner. (MFSA 2011-08 / CVE-2010-1585)

- A JPEG image can be constructed that will 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 2011-09 / CVE-2011-0061)

- 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. (MFSA 2011-10 / CVE-2011-0059)
