This update brings Mozilla SeaMonkey to 1.1.19 fixing various bugs and security issues.

Following security issues are fixed: MFSA 2010-07: Mozilla developers took fixes from previously fixed memory safety bugs in newer Mozilla-based products and ported them to the Mozilla 1.8.1 branch so they can be utilized by Thunderbird 2 and SeaMonkey 1.1.

Paul Fisher reported a crash when joined to an Active Directory server under Vista or Windows 7 and using SSPI authentication.
(CVE-2010-0161) Ludovic Hirlimann reported a crash indexing some messages with attachments (CVE-2010-0163) Carsten Book reported a crash in the JavaScript engine (CVE-2009-3075) Josh Soref reported a crash in the BinHex decoder used on non-Mac platforms. (CVE-2009-3072) monarch2000 reported an integer overflow in a base64 decoding function (CVE-2009-2463)

MFSA 2009-68 / CVE-2009-3983: Security researcher Takehiro Takahashi of the IBM X-Force reported that Mozilla's NTLM implementation was vulnerable to reflection attacks in which NTLM credentials from one application could be forwarded to another arbitary application via the browser. If an attacker could get a user to visit a web page he controlled he could force NTLM authenticated requests to be forwarded to another application on behalf of the user.

MFSA 2009-62 / CVE-2009-3376: Mozilla security researchers Jesse Ruderman and Sid Stamm reported that when downloading a file containing a right-to-left override character (RTL) in the filename, the name displayed in the dialog title bar conflicts with the name of the file shown in the dialog body. An attacker could use this vulnerability to obfuscate the name and file extension of a file to be downloaded and opened, potentially causing a user to run an executable file when they expected to open a non-executable file.

MFSA 2009-59 / CVE-2009-0689: Security researcher Alin Rad Pop of Secunia Research reported a heap-based buffer overflow in Mozilla's string to floating point number conversion routines. Using this vulnerability an attacker could craft some malicious JavaScript code containing a very long string to be converted to a floating point number which would result in improper memory allocation and the execution of an arbitrary memory location. This vulnerability could thus be leveraged by the attacker to run arbitrary code on a victim's computer.

Update: The underlying flaw in the dtoa routines used by Mozilla appears to be essentially the same as that reported against the libc gdtoa routine by Maksymilian Arciemowicz.

MFSA 2010-06 / CVE-2009-3385: Security researcher Georgi Guninski reported that scriptable plugin content, such as Flash objects, could be loaded and executed in SeaMonkey mail messages by embedding the content in an iframe inside the message. If a user were to reply to or forward such a message, malicious JavaScript embedded in the plugin content could potentially steal the contents of the message or files from the local filesystem.

MFSA 2009-49 / CVE-2009-3077: An anonymous security researcher, via TippingPoint's Zero Day Initiative, reported that the columns of a XUL tree element could be manipulated in a particular way which would leave a pointer owned by the column pointing to freed memory. An attacker could potentially use this vulnerability to crash a victim's browser and run arbitrary code on the victim's computer.

The remote Redhat Enterprise Linux 4 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2010:0154 advisory.

    Mozilla Thunderbird is a standalone mail and newsgroup client.

    Several flaws were found in the processing of malformed HTML mail content.
    An HTML mail message containing malicious content could cause Thunderbird     to crash or, potentially, execute arbitrary code with the privileges of the     user running Thunderbird. (CVE-2009-2462, CVE-2009-2463, CVE-2009-2466,     CVE-2009-3072, CVE-2009-3075, CVE-2009-3380, CVE-2009-3979, CVE-2010-0159)

    A use-after-free flaw was found in Thunderbird. An attacker could use this     flaw to crash Thunderbird or, potentially, execute arbitrary code with the     privileges of the user running Thunderbird. (CVE-2009-3077)

    A heap-based buffer overflow flaw was found in the Thunderbird string to     floating point conversion routines. An HTML mail message containing     malicious JavaScript could crash Thunderbird or, potentially, execute     arbitrary code with the privileges of the user running Thunderbird.
    (CVE-2009-0689)

    A use-after-free flaw was found in Thunderbird. Under low memory     conditions, viewing an HTML mail message containing malicious content could     result in Thunderbird executing arbitrary code with the privileges of the     user running Thunderbird. (CVE-2009-1571)

    A flaw was found in the way Thunderbird created temporary file names for     downloaded files. If a local attacker knows the name of a file Thunderbird     is going to download, they can replace the contents of that file with     arbitrary contents. (CVE-2009-3274)

    A flaw was found in the way Thunderbird displayed a right-to-left override     character when downloading a file. In these cases, the name displayed in     the title bar differed from the name displayed in the dialog body. An     attacker could use this flaw to trick a user into downloading a file that     has a file name or extension that is different from what the user expected.
    (CVE-2009-3376)

    A flaw was found in the way Thunderbird processed SOCKS5 proxy replies. A     malicious SOCKS5 server could send a specially-crafted reply that would     cause Thunderbird to crash. (CVE-2009-2470)

    Descriptions in the dialogs when adding and removing PKCS #11 modules were     not informative. An attacker able to trick a user into installing a     malicious PKCS #11 module could use this flaw to install their own     Certificate Authority certificates on a user's machine, making it possible     to trick the user into believing they are viewing trusted content or,     potentially, execute arbitrary code with the privileges of the user running     Thunderbird. (CVE-2009-3076)

    All Thunderbird users should upgrade to this updated package, which     resolves these issues. All running instances of Thunderbird must be     restarted for the update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Multiple vulnerabilities has been found and corrected in mozilla-thunderbird :

Mozilla Thunderbird before 2.0.0.24 and SeaMonkey before 1.1.19 process e-mail attachments with a parser that performs casts and line termination incorrectly, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted message, related to message indexing (CVE-2009-0689).

Integer overflow in a base64 decoding function in Mozilla Firefox before 3.0.12 and Thunderbird allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unspecified vectors (CVE-2009-2463).

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.0.14, and 3.5.x before 3.5.3, allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors (CVE-2009-3072).

Multiple unspecified vulnerabilities in the JavaScript engine in Mozilla Firefox before 3.0.14, and 3.5.x before 3.5.2, allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors (CVE-2009-3075).

Mozilla Firefox before 3.0.14, and 3.5.x before 3.5.3, does not properly manage pointers for the columns (aka TreeColumns) of a XUL tree element, which allows remote attackers to execute arbitrary code via a crafted HTML document, related to a dangling pointer vulnerability. (CVE-2009-3077)

Mozilla Firefox before 3.0.15 and 3.5.x before 3.5.4, and SeaMonkey before 2.0, does not properly handle a right-to-left override (aka RLO or U+202E) Unicode character in a download filename, which allows remote attackers to spoof file extensions via a crafted filename, as demonstrated by displaying a non-executable extension for an executable file (CVE-2009-3376).

Mozilla Firefox before 3.0.16 and 3.5.x before 3.5.6, and SeaMonkey before 2.0.1, allows remote attackers to send authenticated requests to arbitrary applications by replaying the NTLM credentials of a browser user (CVE-2009-3983).

Mozilla Thunderbird before 2.0.0.24 and SeaMonkey before 1.1.19 process e-mail attachments with a parser that performs casts and line termination incorrectly, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted message, related to message indexing (CVE-2010-0163).

This update provides the latest version of Thunderbird which are not vulnerable to these issues.

Packages for 2008.0 and 2009.0 are provided due to the Extended Maintenance Program for those products.

Additionally, some packages which require so, have been rebuilt and are being provided as updates.

Several remote vulnerabilities have been discovered in the Icedove mail client, an unbranded version of the Thunderbird mail client. The Common Vulnerabilities and Exposures project identifies the following problems :

Several flaws were discovered in the JavaScript engine of Thunderbird.
If a user had JavaScript enabled and were tricked into viewing malicious web content, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-0689, CVE-2009-2463, CVE-2009-3075)

Josh Soref discovered that the BinHex decoder used in Thunderbird contained a flaw. If a user were tricked into viewing malicious content, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-3072)

It was discovered that Thunderbird did not properly manage memory when using XUL tree elements. If a user were tricked into viewing malicious content, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-3077)

Jesse Ruderman and Sid Stamm discovered that Thunderbird did not properly display filenames containing right-to-left (RTL) override characters. If a user were tricked into opening a malicious file with a crafted filename, an attacker could exploit this to trick the user into opening a different file than the user expected. (CVE-2009-3376)

Takehiro Takahashi discovered flaws in the NTLM implementation in Thunderbird. If an NTLM authenticated user opened content containing links to a malicious website, a remote attacker could send requests to other applications, authenticated as the user. (CVE-2009-3983)

Ludovic Hirlimann discovered a flaw in the way Thunderbird indexed certain messages with attachments. A remote attacker could send specially crafted content and cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2010-0163).

An updated thunderbird package that fixes several security issues is now available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having moderate 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.

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed HTML mail content. An HTML mail message containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2009-2462, CVE-2009-2463, CVE-2009-2466, CVE-2009-3072, CVE-2009-3075, CVE-2009-3380, CVE-2009-3979, CVE-2010-0159)

A use-after-free flaw was found in Thunderbird. An attacker could use this flaw to crash Thunderbird or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2009-3077)

A heap-based buffer overflow flaw was found in the Thunderbird string to floating point conversion routines. An HTML mail message containing malicious JavaScript could crash Thunderbird or, potentially, execute arbitrary code with the privileges of the user running Thunderbird.
(CVE-2009-0689)

A use-after-free flaw was found in Thunderbird. Under low memory conditions, viewing an HTML mail message containing malicious content could result in Thunderbird executing arbitrary code with the privileges of the user running Thunderbird. (CVE-2009-1571)

A flaw was found in the way Thunderbird created temporary file names for downloaded files. If a local attacker knows the name of a file Thunderbird is going to download, they can replace the contents of that file with arbitrary contents. (CVE-2009-3274)

A flaw was found in the way Thunderbird displayed a right-to-left override character when downloading a file. In these cases, the name displayed in the title bar differed from the name displayed in the dialog body. An attacker could use this flaw to trick a user into downloading a file that has a file name or extension that is different from what the user expected. (CVE-2009-3376)

A flaw was found in the way Thunderbird processed SOCKS5 proxy replies. A malicious SOCKS5 server could send a specially crafted reply that would cause Thunderbird to crash. (CVE-2009-2470)

Descriptions in the dialogs when adding and removing PKCS #11 modules were not informative. An attacker able to trick a user into installing a malicious PKCS #11 module could use this flaw to install their own Certificate Authority certificates on a user's machine, making it possible to trick the user into believing they are viewing trusted content or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2009-3076)

All Thunderbird users should upgrade to this updated package, which resolves these issues. All running instances of Thunderbird must be restarted for the update to take effect.
