Impact A number of memory corruption vulnerabilities have been found in the Mozilla application which may allow a remote user who is able to create a web page which is visited by a local user using the Mozilla browser, or who sends a specially crafted email that is read by a local user using Mozilla, to either cause the Mozilla application to crash or execute arbitrary code with the privileges of the user running Mozilla. The ability of a remote user to cause the Mozilla application to crash is a type of Denial of Service (DoS). The following Mozilla advisory describes ten separate memory corruption issues: * http://www.mozilla.org/security/announce/mfsa2006-32.html This Sun Alert corresponds to four of the issues described in the Mozilla advisory above: Memory corruption involving BoxObjects (Neil Rashbrook): * https://bugzilla.mozilla.org/show_bug.cgi?id=329219 Memory corruption involving BoxObjects (Boris Zbarsky): * https://bugzilla.mozilla.org/show_bug.cgi?id=326931 Potential integer overflow in jsstr tagify (Georgi Guninski): * https://bugzilla.mozilla.org/show_bug.cgi?id=335535 Content-implemented tree views can corrupt memory (Boris Zbarsky): * https://bugzilla.mozilla.org/show_bug.cgi?id=326501 Additional references: CVE-2006-2779 describes nine of the ten issues documented in Mozilla advisory MFSA 2006-32 which includes the above issues 329219, 326931, and 326501. * http://cve.mitre.org/cgi-bin/cvename.cgi?name=2006-2779 CVE-2006-2780 describes the tenth issue documented in Mozilla advisory MFSA 2006-32, the integer overflow in the jsstr tagify, 335535. * http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2780 CERT VU#466673 references all ten issues described in Mozilla advisory MFSA 2006-32. * http://www.kb.cert.org/vuls/id/466673 2.

Customers are advised to upgrade to Mozilla 1.7 to get these security fixes. To determine the version of Mozilla on a Solaris system, the following command can be run: % /usr/sfw/bin/mozilla -version Mozilla 1.7, (Sun Java Desktop System), build 2005031721 3.
