Several security related problems have been discovered in Mozilla. The Common Vulnerabilities and Exposures project identifies the following vulnerabilities: CVE-2006-1942 Eric Foley discovered that a user can be tricked to expose a local file to a remote attacker by displaying a local file as image in connection with other vulnerabilities. [MFSA-2006-39] CVE-2006-2775 XUL attributes are associated with the wrong URL under certain circumstances, which might allow remote attackers to bypass restrictions. [MFSA-2006-35] CVE-2006-2776 Paul Nickerson discovered that content-defined setters on an object prototype were getting called by privileged user interface code, and moz_bug_r_a4 demonstrated that the higher privilege level could be passed along to the content-defined attack code. [MFSA-2006-37] CVE-2006-2777 A vulnerability allows remote attackers to execute arbitrary code and create notifications that are executed in a privileged context. [MFSA-2006-43] CVE-2006-2778 Mikolaj Habryn discovered a buffer overflow in the crypto.signText function that allows remote attackers to execute arbitrary code via certain optional Certificate Authority name arguments. [MFSA-2006-38] CVE-2006-2779 Mozilla team members discovered several crashes during testing of the browser engine showing evidence of memory corruption which may also lead to the execution of arbitrary code. This problem has only partially been corrected. [MFSA-2006-32] CVE-2006-2780 An integer overflow allows remote attackers to cause a denial of service and may permit the execution of arbitrary code. [MFSA-2006-32] CVE-2006-2781 Masatoshi Kimura discovered a double-free vulnerability that allows remote attackers to cause a denial of service and possibly execute arbitrary code via a VCard. [MFSA-2006-40] CVE-2006-2782 Chuck McAuley discovered that a text input box can be pre-filled with a filename and then turned into a file-upload control, allowing a malicious website to steal any local file whose name they can guess. [MFSA-2006-41, MFSA-2006-23, CVE-2006-1729] CVE-2006-2783 Masatoshi Kimura discovered that the Unicode Byte-order-Mark (BOM) is stripped from UTF-8 pages during the conversion to Unicode before the parser sees the web page, which allows remote attackers to conduct cross-site scripting (XSS) attacks. [MFSA-2006-42] CVE-2006-2784 Paul Nickerson discovered that the fix for CVE-2005-0752 can be bypassed using nested javascript: URLs, allowing the attacker to execute privileged code. [MFSA-2005-34, MFSA-2006-36] CVE-2006-2785 Paul Nickerson demonstrated that if an attacker could convince a user to right-click on a broken image and choose View Image from the context menu then he could get JavaScript to run. [MFSA-2006-34] CVE-2006-2786 Kazuho Oku discovered that Mozilla's lenient handling of HTTP header syntax may allow remote attackers to trick the browser to interpret certain responses as if they were responses from two different sites. [MFSA-2006-33] CVE-2006-2787 The Mozilla researcher moz_bug_r_a4 discovered that JavaScript run via EvalInSandbox can escape the sandbox and gain elevated privilege. [MFSA-2006-31] For the stable distribution (sarge) these problems have been fixed in version 1.7.8-1sarge7.1. For the unstable distribution (sid) these problems have been fixed in version 1.7.13-0.3. We recommend that you upgrade your Mozilla packages.
