The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2009:1531 advisory.

    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 creates temporary file names for     downloaded files. If a local attacker knows the name of a file SeaMonkey is     going to download, they can replace the contents of that file with     arbitrary contents. (CVE-2009-3274)

    A heap-based buffer overflow flaw was found in the SeaMonkey string to     floating point conversion routines. A web page containing malicious     JavaScript could crash SeaMonkey or, potentially, execute arbitrary code     with the privileges of the user running SeaMonkey. (CVE-2009-1563)

    A flaw was found in the way SeaMonkey handles text selection. A malicious     website may be able to read highlighted text in a different domain (e.g.
    another website the user is viewing), bypassing the same-origin policy.
    (CVE-2009-3375)

    A flaw was found in the way SeaMonkey displays a right-to-left override     character when downloading a file. In these cases, the name displayed in     the title bar differs 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 differs from what the user expected.
    (CVE-2009-3376)

    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-2009-3380)

    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.

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.

The installed version of SeaMonkey is earlier than 1.1.19.  Such versions are potentially affected by the following security issues :
  - The columns of a XUL tree element can be manipulated in     a particular way that would leave a pointer owned by     the column pointing to freed memory. (MFSA 2009-49)

  - A heap-based buffer overflow exists in Mozilla's string     to floating point number conversion routines.     (MFSA 2009-59)

  - It is possible to obfuscate the name of files to be     downloaded by using a right-to-left override character     (RTL). (MFSA 2009-62)

  - Mozilla's NTLM implementation is vulnerable to     reflection attacks in which NTLM credentials from one     application could be forwarded to another arbitrary     application. (MFSA 2009-68)

  - Scriptable plugin content, such as Flash objects, can be     loaded and executed by embedding the content in an     iframe inside the message. (MFSA 2010-06)

  - Multiple memory corruption vulnerabilities exist that     may result in the execution of arbitrary code.     (MFSA 2010-07)

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.
