Heap-based buffer overflow in Mozilla Firefox 2.x before 2.0.0.1, 1.5.x before 1.5.0.9, Thunderbird before 1.5.0.9, and SeaMonkey before 1.0.7 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by setting the CSS cursor to certain images that cause an incorrect size calculation when converting to a Windows bitmap.

This update brings MozillaFirefox to the security update release 1.5.0.9, including the following security fixes.

Various flaws have been reported that allow an attacker to execute arbitrary code with user privileges or bypass internal XSS protections by tricking the user into opening a malicious email containing JavaScript. Please note that JavaScript is disabled by default for emails, and it is not recommended to enable it. (CVE-2006-6497, CVE-2006-6498, CVE-2006-6499, CVE-2006-6501, CVE-2006-6502, CVE-2006-6503).

The remote host is affected by the vulnerability described in GLSA-200701-04 (SeaMonkey: Multiple vulnerabilities)

    An anonymous researcher found evidence of memory corruption in the way     SeaMonkey handles certain types of SVG comment DOM nodes. Georgi     Guninski and David Bienvenu discovered buffer overflows in the     processing of long 'Content-Type:' and long non-ASCII MIME email     headers. Additionally, Frederik Reiss discovered a heap-based buffer     overflow in the conversion of a CSS cursor. Several other issues with     memory corruption were also fixed. SeaMonkey also contains less severe     vulnerabilities involving JavaScript and Java.
  Impact :

    An attacker could entice a user to load malicious JavaScript or a     malicious web page with a SeaMonkey application, possibly leading to     the execution of arbitrary code with the rights of the user running     those products. An attacker could also perform cross-site scripting     attacks, leading to the exposure of sensitive information, like user     credentials. Note that the execution of JavaScript or Java applets is     disabled by default in the SeaMonkey email client, and enabling it is     strongly discouraged.
  Workaround :

    There are no known workarounds for all the issues at this time.

The remote host is affected by the vulnerability described in GLSA-200701-03 (Mozilla Thunderbird: Multiple vulnerabilities)

    Georgi Guninski and David Bienvenu discovered buffer overflows in the     processing of long 'Content-Type:' and long non-ASCII MIME headers.
    Additionally, Frederik Reiss discovered a heap-based buffer overflow in     the conversion of a CSS cursor. Different vulnerabilities involving     memory corruption in the browser engine were also fixed. Mozilla     Thunderbird also contains less severe vulnerabilities involving     JavaScript and Java.
  Impact :

    An attacker could entice a user to view a specially crafted email that     will trigger one of these vulnerabilities, possibly leading to the     execution of arbitrary code. An attacker could also perform cross-site     scripting attacks, leading to the exposure of sensitive information,     like user credentials. Note that the execution of JavaScript or Java     applets is disabled by default and enabling it is strongly discouraged.
  Workaround :

    There are no known workarounds for all the issues at this time.
