SynopsisThe remote SuSE 10 host is missing a security-related patch.
DescriptionThis update brings Mozilla Firefox to version 3.5.15, fixing various bugs and security issues.
The following security issues were fixed :
- 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. (MFSA 2010-49 / CVE-2010-3169)
- Security researcher Chris Rohlf of Matasano Security reported that the implementation of the HTML frameset element contained an integer overflow vulnerability. The code responsible for parsing the frameset columns used an 8-byte counter for the column numbers, so when a very large number of columns was passed in the counter would overflow. When this counter was subsequently used to allocate memory for the frameset, the memory buffer would be too small, potentially resulting in a heap buffer overflow and execution of attacker-controlled memory. (MFSA 2010-50 / CVE-2010-2765)
- Security researcher Sergey Glazunov reported a dangling pointer vulnerability in the implementation of navigator.plugins in which the navigator object could retain a pointer to the plugins array even after it had been destroyed. An attacker could potentially use this issue to crash the browser and run arbitrary code on a victim's computer. (MFSA 2010-51 / CVE-2010-2767)
- Security researcher Haifei Li of FortiGuard Labs reported that Firefox could be used to load a malicious code library that had been planted on a victim's computer. Firefox attempts to load dwmapi.dll upon startup as part of its platform detection, so on systems that don't have this library, such as Windows XP, Firefox will subsequently attempt to load the library from the current working directory. An attacker could use this vulnerability to trick a user into downloading a HTML file and a malicious copy of dwmapi.dll into the same directory on their computer and opening the HTML file with Firefox, thus causing the malicious code to be executed. If the attacker was on the same network as the victim, the malicious DLL could also be loaded via a UNC path. The attack also requires that Firefox not currently be running when it is asked to open the HTML file and accompanying DLL. As this is a Windows only problem, it does not affect the Linux version. It is listed for completeness only. (MFSA 2010-52 / CVE-2010-3131)
- Security researcher wushi of team509 reported a heap buffer overflow in code routines responsible for transforming text runs. A page could be constructed with a bidirectional text run which upon reflow could result in an incorrect length being calculated for the run of text. When this value is subsequently used to allocate memory for the text too small a buffer may be created potentially resulting in a buffer overflow and the execution of attacker controlled memory. (MFSA 2010-53 / CVE-2010-3166)
- Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that there was a remaining dangling pointer issue leftover from the fix to CVE-2010-2753. Under certain circumstances one of the pointers held by a XUL tree selection could be freed and then later reused, potentially resulting in the execution of attacker-controlled memory. (MFSA 2010-54 / CVE-2010-2760)
- Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that XUL objects could be manipulated such that the setting of certain properties on the object would trigger the removal of the tree from the DOM and cause certain sections of deleted memory to be accessed. In products based on Gecko version 1.9.2 (Firefox 3.6, Thunderbird 3.1) and newer this memory has been overwritten by a value that will cause an unexploitable crash. In products based on Gecko version 1.9.1 (Firefox 3.5, Thunderbird 3.0, and SeaMonkey 2.0) and older an attacker could potentially use this vulnerability to crash a victim's browser and run arbitrary code on their computer. (MFSA 2010-55 / CVE-2010-3168)
- Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that the implementation of XUL's content view contains a dangling pointer vulnerability. One of the content view's methods for accessing the internal structure of the tree could be manipulated into removing a node prior to accessing it, resulting in the accessing of deleted memory. If an attacker can control the contents of the deleted memory prior to its access they could use this vulnerability to run arbitrary code on a victim's machine. (MFSA 2010-56 / CVE-2010-3167)
- Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that code used to normalize a document contained a logical flaw that could be leveraged to run arbitrary code. When the normalization code ran, a static count of the document's child nodes was used in the traversal, so a page could be constructed that would remove DOM nodes during this normalization which could lead to the accessing of a deleted object and potentially the execution of attacker-controlled memory. (MFSA 2010-57 / CVE-2010-2766)
- Security researcher Marc Schoenefeld reported that a specially crafted font could be applied to a document and cause a crash on Mac systems. The crash showed signs of memory corruption and presumably could be used by an attacker to execute arbitrary code on a victim's computer. This issue probably does not affect the Linux builds and so is listed for completeness. (MFSA 2010-58 / CVE-2010-2770)
- Mozilla security researcher mozbugr_a4 reported that the wrapper class XPCSafeJSObjectWrapper (SJOW) on the Mozilla 1.9.1 development branch has a logical error in its scripted function implementation that allows the caller to run the function within the context of another site. This is a violation of the same-origin policy and could be used to mount an XSS attack. (MFSA 2010-60 / CVE-2010-2763)
- Matt Haggard reported that the statusText property of an XMLHttpRequest object is readable by the requestor even when the request is made across origins. This status information reveals the presence of a web server and could be used to gather information about servers on internal private networks. This issue was also independently reported to Mozilla by Nicholas Berthaume.
(MFSA 2010-63 / CVE-2010-2764)
- 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.

Paul Nickerson, Jesse Ruderman, Olli Pettay, Igor Bukanov and Josh Soref reported memory safety problems that affected Firefox 3.6 and Firefox 3.5.
o Memory safety bugs - Firefox 3.6, Firefox 3.5 o CVE-2010-3176
Jesse Ruderman reported a crash which affected Firefox 3.5 only.
o https://bugzilla.mozilla.org/show_bug.cgi?id=476547 o CVE-2010-3174
- Security researcher Alexander Miller reported that passing an excessively long string to document.write could cause text rendering routines to end up in an inconsistent state with sections of stack memory being overwritten with the string data. An attacker could use this flaw to crash a victim's browser and potentially run arbitrary code on their computer. (MFSA 2010-65 / CVE-2010-3179)
- Security researcher Sergey Glazunov reported that it was possible to access the locationbar property of a window object after it had been closed. Since the closed window's memory could have been subsequently reused by the system it was possible that an attempt to access the locationbar property could result in the execution of attacker-controlled memory. (MFSA 2010-66 / CVE-2010-3180)
(MFSA 2010-69 / CVE-2010-3178)
- Security researcher Richard Moore reported that when an SSL certificate was created with a common name containing a wildcard followed by a partial IP address a valid SSL connection could be established with a server whose IP address matched the wildcard range by browsing directly to the IP address. It is extremely unlikely that such a certificate would be issued by a Certificate Authority. (MFSA 2010-70 / CVE-2010-3170)
- Dmitri Gribenko reported that the script used to launch Mozilla applications on Linux was effectively including the current working directory in the LD_LIBRARY_PATH environment variable. If an attacker was able to place into the current working directory a malicious shared library with the same name as a library that the bootstrapping script depends on the attacker could have their library loaded instead of the legitimate library.
