SuSE 10 Security Update : Mozilla Firefox (ZYPP Patch Number 8381)

critical Nessus Plugin ID 63091

Language:

Synopsis

The remote SuSE 10 host is missing a security-related patch.

Description

Mozilla Firefox has been updated to the 10.0.11 ESR security release, which fixes various bugs and security issues.

- Security researcher miaubiz used the Address Sanitizer tool to discover a series critically rated of use-after-free, buffer overflow, and memory corruption issues in shipped software. These issues are potentially exploitable, allowing for remote code execution. We would also like to thank miaubiz for reporting two additional use-after-free and memory corruption issues introduced during Firefox development that have been fixed before general release. (MFSA 2012-106)

In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products.

The following issues have been fixed in Firefox 17 and ESR 10.0.11 :

o use-after-free when loading html file on osx (CVE-2012-5830) o Mesa crashes on certain texImage2D calls involving level>0 (CVE-2012-5833) o integer overflow, invalid write w/webgl bufferdata. (CVE-2012-5835)

The following issues have been fixed in Firefox 17 :

o crash in copyTexImage2D with image dimensions too large for given level. (CVE-2012-5838)

- Security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team discovered a series critically rated of use-after-free and buffer overflow issues using the Address Sanitizer tool in shipped software. These issues are potentially exploitable, allowing for remote code execution. We would also like to thank Abhishek for reporting five additional use-after-free, out of bounds read, and buffer overflow flaws introduced during Firefox development that have been fixed before general release.

The following issues have been fixed in Firefox 17 and ESR 10.0.11 :

o Heap-use-after-free in nsTextEditorState::PrepareEditor (CVE-2012-4214) o Heap-use-after-free in nsPlaintextEditor::FireClipboardEvent (CVE-2012-4215) o Heap-use-after-free in gfxFont::GetFontEntry (CVE-2012-4216) o Heap-buffer-overflow in nsWindow::OnExposeEvent (CVE-2012-5829) o heap-buffer-overflow in gfxShapedWord::CompressedGlyph::IsClusterStart o CVE-2012-5839 o Heap-use-after-free in nsTextEditorState::PrepareEditor. (CVE-2012-5840)

The following issues have been fixed in Firefox 17 :

o Heap-use-after-free in XPCWrappedNative::Mark (CVE-2012-4212) o Heap-use-after-free in nsEditor::FindNextLeafNode (CVE-2012-4213) o Heap-use-after-free in nsViewManager::ProcessPendingUpdates (CVE-2012-4217) o Heap-use-after-free BuildTextRunsScanner::BreakSink::SetBreaks. (CVE-2012-4218)

- Security researcher Mariusz Mlynski reported that when a maliciously crafted stylesheet is inspected in the Style Inspector, HTML and CSS can run in a chrome privileged context without being properly sanitized first. This can lead to arbitrary code execution. (MFSA 2012-104 / CVE-2012-4210)

- Security researcher Mariusz Mlynski reported that the location property can be accessed by binary plugins through top.location with a frame whose name attribute's value is set to 'top'. This can allow for possible cross-site scripting (XSS) attacks through plugins.
(MFSA 2012-103 / CVE-2012-4209)

In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products.

- Security researcher Masato Kinugawa reported that when script is entered into the Developer Toolbar, it runs in a chrome privileged context. This allows for arbitrary code execution or cross-site scripting (XSS) if a user can be convinced to paste malicious code into the Developer Toolbar. (MFSA 2012-102 / CVE-2012-5837)

- Security researcher Masato Kinugawa found when HZ-GB-2312 charset encoding is used for text, the '~' character will destroy another character near the chunk delimiter. This can lead to a cross-site scripting (XSS) attack in pages encoded in HZ-GB-2312. (MFSA 2012-101 / CVE-2012-4207)

- Mozilla developer Bobby Holley reported that security wrappers filter at the time of property access, but once a function is returned, the caller can use this function without further security checks. This affects cross-origin wrappers, allowing for write actions on objects when only read actions should be properly allowed. This can lead to cross-site scripting (XSS) attacks. (MFSA 2012-100 / CVE-2012-5841)

In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products.

- Mozilla developer Peter Van der Beken discovered that same-origin XrayWrappers expose chrome-only properties even when not in a chrome compartment. This can allow web content to get properties of DOM objects that are intended to be chrome-only. (MFSA 2012-99 / CVE-2012-4208)

In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products.

- Security researcher Robert Kugler reported that when a specifically named DLL file on a Windows computer is placed in the default downloads directory with the Firefox installer, the Firefox installer will load this DLL when it is launched. In circumstances where the installer is run by an administrator privileged account, this allows for the downloaded DLL file to be run with administrator privileges. This can lead to arbitrary code execution from a privileged account. (MFSA 2012-98 / CVE-2012-4206)

- Mozilla developer Gabor Krizsanits discovered that XMLHttpRequest objects created within sandboxes have the system principal instead of the sandbox principal. This can lead to cross-site request forgery (CSRF) or information theft via an add-on running untrusted code in a sandbox. (MFSA 2012-97 / CVE-2012-4205)

- Security researcher Scott Bell of Security-Assessment.com used the Address Sanitizer tool to discover a memory corruption in str_unescape in the JavaScript engine. This could potentially lead to arbitrary code execution. (MFSA 2012-96 / CVE-2012-4204)

In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products.

- Security researcher [email protected] reported that if a javascript: URL is selected from the list of Firefox 'new tab' page, the script will inherit the privileges of the privileged 'new tab' page. This allows for the execution of locally installed programs if a user can be convinced to save a bookmark of a malicious javascript:
URL. (MFSA 2012-95 / CVE-2012-4203)

- Security researcher Jonathan Stephens discovered that combining SVG text on a path with the setting of CSS properties could lead to a potentially exploitable crash. (MFSA 2012-94 / CVE-2012-5836)

- Mozilla security researcher moz_bug_r_a4 reported that if code executed by the evalInSandbox function sets location.href, it can get the wrong subject principal for the URL check, ignoring the sandbox's JavaScript context and gaining the context of evalInSandbox object.
This can lead to malicious web content being able to perform a cross-site scripting (XSS) attack or stealing a copy of a local file if the user has installed an add-on vulnerable to this attack. (MFSA 2012-93 / CVE-2012-4201)

- Security researcher Atte Kettunen from OUSPG used the Address Sanitizer tool to discover a buffer overflow while rendering GIF format images. This issue is potentially exploitable and could lead to arbitrary code execution. (MFSA 2012-92 / CVE-2012-4202)

- 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 2012-91)
