1. Topic:

Updated mozilla, galeon and epiphany packages that fix multiple vulnerabilities are now available.

Mozilla is an open-source Web browser, designed for standards compliance, performance, and portability.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386

3. Problem description:

Note that some of these issues have already been fixed in Redhat 9 and Fedora Core 1. Please refer to previous advisories for details.

NISCC testing of implementations of the S/MIME protocol uncovered a number of bugs in NSS versions prior to 3.9. The parsing of unexpected ASN.1 constructs within S/MIME data could cause Mozilla to crash or consume large amounts of memory. A remote attacker could potentially trigger these bugs by sending a carefully-crafted S/MIME message to a victim. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2003-0564 to this issue.

Andreas Sandblad discovered a cross-site scripting issue that affects various versions of Mozilla. When linking to a new page it is still possible to interact with the old page before the new page has been successfully loaded. Any Javascript events will be invoked in the context of the new page, making cross-site scripting possible if the different pages belong to different domains. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2004-0191 to this issue.

Flaws have been found in the cookie path handling between a number of Web browsers and servers. The HTTP cookie standard allows a Web server supplying a cookie to a client to specify a subset of URLs on the origin server to which the cookie applies. Web servers such as Apache do not filter returned cookies and assume that the client will only send back cookies for requests that fall within the server-supplied subset of URLs. However, by supplying URLs that use path traversal (/../) and character encoding, it is possible to fool many browsers into sending a cookie to a path outside of the originally-specified subset. The Common
Vulnerabilities and Exposures project ( has assigned the name CAN-2003-0594 to this issue.

Zen Parse reported improper input validation to the SOAPParameter object constructor leading to an integer overflow and controllable heap corruption. Malicious JavaScript could be written to utilize this flaw and could allow arbitrary code execution. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2004-0722 to this issue.

During a source code audit, Chris Evans discovered a buffer overflow and integer overflows which affect the libpng code inside Mozilla. An attacker could create a carefully crafted PNG file in such a way that it would cause Mozilla to crash or execute arbitrary code when the image was viewed. (CAN-2004-0597, CAN-2004-0599)

Zen Parse reported a flaw in the POP3 capability. A malicious POP3 server could send a carefully crafted response that would cause a heap overflow and potentially allow execution of arbitrary code as the user running Mozilla. (CAN-2004-0757)

Marcel Boesch found a flaw that allows a CA certificate to be imported with a DN the same as that of the built-in CA root certificates, which can cause a denial of service to SSL pages, as the malicious certificate is treated as invalid. (CAN-2004-0758)

Met - Martin Hassman reported a flaw in Mozilla that could allow malicious Javascript code to upload local files from a users machine without requiring confirmation. (CAN-2004-0759)

Mindlock Security reported a flaw in ftp URI handling. By using a NULL character (%00) in a ftp URI, Mozilla can be confused into opening a resource as a different MIME type. (CAN-2004-0760)

Mozilla does not properly prevent a frame in one domain from injecting content into a frame that belongs to another domain, which facilitates website spoofing and other attacks, also known as the frame injection vulnerability. (CAN-2004-0718)

Tolga Tarhan reported a flaw that can allow a malicious webpage to use a redirect sequence to spoof the security lock icon that makes a webpage appear to be encrypted. (CAN-2004-0761)

Jesse Ruderman reported a security issue that affects a number of browsers
including Mozilla that could allow malicious websites to install arbitrary
extensions by using interactive events to manipulate the XPInstall Security
dialog box. (CAN-2004-0762)

Emmanouel Kellinis discovered a caching flaw in Mozilla which allows malicious websites to spoof certificates of trusted websites via redirects and Javascript that uses the "onunload" method. (CAN-2004-0763)

Mozilla allowed malicious websites to hijack the user interface via the "chrome" flag and XML User Interface Language (XUL) files. (CAN-2004-0764)

The cert_TestHostName function in Mozilla only checks the hostname portion of a certificate when the hostname portion of the URI is not a fully qualified domain name (FQDN). This flaw could be used for spoofing if an attacker had control of machines on a default DNS search path. (CAN-2004-07

Jesse Ruderman discovered a cross-domain scripting bug in Mozilla. If a user is tricked into dragging a javascript link into another frame or page, it becomes possible for an attacker to steal or modify sensitive information from that site. Additionally, if a user is tricked into dragging two links in sequence to another window (not frame), it is possible for the attacker to execute arbitrary commands. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2004-0905 to this issue.

Gael Delalleau discovered an integer overflow which affects the BMP handling code inside Mozilla. An attacker could create a carefully crafted BMP file in such a way that it would cause Mozilla to crash or execute arbitrary code when the image is viewed. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2004-0904 to this issue.

Georgi Guninski discovered a stack-based buffer overflow in the vCard display routines. An attacker could create a carefully crafted vCard file in such a way that it would cause Mozilla to crash or execute arbitrary code when viewed. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2004-0903 to this issue.

Wladimir Palant discovered a flaw in the way javascript interacts with the clipboard. It is possible that an attacker could use malicious javascript code to steal sensitive data which has been copied into the clipboard. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2004-0908 to this issue.

Georgi Guninski discovered a heap based buffer overflow in the "Send Page" feature. It is possible that an attacker could construct a link in such a way that a user attempting to forward it could result in a crash or arbitrary code execution. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2004-0902 to this issue.

4. Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains
the desired RPMs.

Please note that this update is also available via yum and apt. Many people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit for directions on how to configure yum and apt-get.
