Updated SeaMonkey packages that fix several security issues are now available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

SeaMonkey is an open source web browser, email and newsgroup client, IRC chat client, and HTML editor.

A flaw was found in the way SeaMonkey handled malformed JPEG images. A website containing a malicious JPEG image could cause SeaMonkey to crash or, potentially, execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2011-2377)

Multiple dangling pointer flaws were found in SeaMonkey. A web page containing malicious content could cause SeaMonkey to crash or, potentially, execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2011-0083, CVE-2011-0085, CVE-2011-2363)

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause SeaMonkey to crash or, potentially, execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2011-2364, CVE-2011-2365, CVE-2011-2374, CVE-2011-2375, CVE-2011-2376)

An integer overflow flaw was found in the way SeaMonkey handled JavaScript Array objects. A website containing malicious JavaScript could cause SeaMonkey to execute that JavaScript with the privileges of the user running SeaMonkey. (CVE-2011-2371)

A use-after-free flaw was found in the way SeaMonkey handled malformed JavaScript. A website containing malicious JavaScript could cause SeaMonkey to execute that JavaScript with the privileges of the user running SeaMonkey. (CVE-2011-2373)

It was found that SeaMonkey could treat two separate cookies as interchangeable if both were for the same domain name but one of those domain names had a trailing '.' character. This violates the same-origin policy and could possibly lead to data being leaked to the wrong domain. (CVE-2011-2362)

All SeaMonkey users should upgrade to these updated packages, which correct these issues. After installing the update, SeaMonkey must be restarted for the changes to take effect.

The installed version of SeaMonkey is earlier than 2.2.0.  As such, it is potentially affected by the following security issues :

  - Errors in the WebGL implementation can allow the     loading of WebGL textures from cross-domain images or     allow the crash of the application and execution of     arbitrary code. (CVE-2011-2366, CVE-2011-2368)

  - An out-of-bounds read error exists in the WebGL     implementation that can lead to crashes and may allow     an attacker to read arbitrary data from the GPU,     including that of other processes. (CVE-2011-2367)

  - An error exists in the decoding of HTML-encoded     entities contained in SVG elements. This error could lead     to cross-site scripting attacks. (CVE-2011-2369)

  - An unspecified error exists that allows non-whitelisted     sites to trigger an install dialog for add-ons and     themes. (CVE-2011-2370)

  - When a JavaScript Array object has its length set to an     extremely large value, the iteration of array elements     that occurs when its reduceRight method is called could     result in code execution due to an invalid index value     being used. (CVE-2011-2371)

  - A use-after-free error when viewing XUL documents with     scripts disabled could lead to code execution.
    (CVE-2011-2373)

  - Multiple memory safety issues can lead to application     crashes and possibly remote code execution.
    (CVE-2011-2375)

  - A memory corruption issue due to multipart /     x-mixed-replace images could lead to memory corruption.
    (CVE-2011-2377)

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2011-275:04 advisory.

    Mozilla Firefox is an open-source web browser, designed for standards compliance, performance and     portability.
    Security issues fixed with this release:
    CVE-2011-0083     Use-after-free vulnerability in the nsSVGPathSegList::ReplaceItem function in the implementation of SVG     element lists in Mozilla Firefox before 3.6.18, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14     allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary     code via vectors involving a user-supplied callback.
    CVE-2011-0085     Use-after-free vulnerability in the nsXULCommandDispatcher function in Mozilla Firefox before 3.6.18,     Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 allows remote attackers to execute arbitrary code     via a crafted XUL document that dequeues the current command updater.

    CVE-2011-2363     Use-after-free vulnerability in the nsSVGPointList::AppendElement function in the implementation of SVG     element lists in Mozilla Firefox before 3.6.18, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14     allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary     code via vectors involving a user-supplied callback.
    CVE-2011-2364     Unspecified vulnerability in the browser engine in Mozilla Firefox 3.6.x before 3.6.18 and Thunderbird     before 3.1.11 allows remote attackers to cause a denial of service (memory corruption and application     crash) or possibly execute arbitrary code via unknown vectors, a different vulnerability than     CVE-2011-2365.

    CVE-2011-2371     Integer overflow in the Array.reduceRight method in Mozilla Firefox before 3.6.18 and 4.x through 4.0.1,     Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 allows remote attackers to execute arbitrary code     via vectors involving a long JavaScript Array object.
    CVE-2011-2373     Use-after-free vulnerability in Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, Thunderbird before     3.1.11, and SeaMonkey through 2.0.14, when JavaScript is disabled, allows remote attackers to execute     arbitrary code via a crafted XUL document.
    CVE-2011-2374     Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.6.18 and 4.x     through 4.0.1, and Thunderbird before 3.1.11, allow remote attackers to cause a denial of service (memory     corruption and application crash) or possibly execute arbitrary code via unknown vectors.
    CVE-2011-2375     Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 5.0 and Thunderbird     through 3.1.11 allow remote attackers to cause a denial of service (memory corruption and application     crash) or possibly execute arbitrary code via unknown vectors.
    CVE-2011-2376     Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.6.18 and     Thunderbird before 3.1.11 allow remote attackers to cause a denial of service (memory corruption and     application crash) or possibly execute arbitrary code via unknown vectors.
    CVE-2011-2377     Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, Thunderbird before 3.1.11, and SeaMonkey through     2.0.14 allow remote attackers to cause a denial of service (memory corruption and application crash) or     possibly execute arbitrary code via a multipart/x-mixed-replace image.
    CVE-2011-2605     CRLF injection vulnerability in the nsCookieService::SetCookieStringInternal function in     netwerk/cookie/nsCookieService.cpp in Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, and Thunderbird     before 3.1.11, allows remote attackers to bypass intended access restrictions via a string containing a n     (newline) character, which is not properly handled in a JavaScript document.cookie = expression, a     different vulnerability than CVE-2011-2374.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

  - It is possible for an image from a different domain to     be loaded into a WebGL texture which could be used to     steal image data from a different site. (CVE-2011-2366,     CVE-2011-2598)

  - An out-of-bounds read issue and an invalid write issue     could cause the application to crash. (CVE-2011-2367,     CVE-2011-2368)
