Posted on: 10/06/2004 11:47 AM

An updated Mozilla package is available for SUSE Linux ______________________________________________________________________________ SUSE Security Announcement Package: mozilla Announcement-ID: SUSE-SA:2004:036 Date: Wednesday, Oct 6th 14:36:39 MEST 2004 Affected products: 8.1, 8.2, 9.0, 9.1 SUSE Linux Enterprise Server 8, 9 SUSE Linux Desktop 1.0 Vulnerability Type: various vulnerabilities Severity (1-10): 5 SUSE default package: yes Cross References: Content of this advisory: 1) security vulnerability resolved: - various vulnerabilities problem description 2) solution/workaround 3) special instructions and notes 4) package location and checksums 5) pending vulnerabilities, solutions, workarounds: - openmotif 6) standard appendix (further information)

_____________________________________________________________________________ 1) problem description, brief discussion During the last months a number of security problems have been fixed in Mozilla and Mozilla based brwosers. These include: - CAN-2004-0718: content in unrelated windows could be modified - CAN-2004-0722: integer overflow in the SOAPParameter object constructor - CAN-2004-0757: heap-based buffer overflow in the SendUidl of POP3 code - CAN-2004-0758: denial-of-service with malicious SSL certificates - CAN-2004-0759: read files via java script  - CAN-2004-0760: MIME code handles %00 incorrectly - CAN-2004-0761: spoofing of security lock icon - CAN-2004-0762: manipulation of XPInstall Security dialog box - CAN-2004-0763: spoofing of SSL certificates by using redirects and java script  - CAN-2004-0764: hijacking the user interface via the "chrome" flag and XML User Interface Language (XUL) files - CAN-2004-0765: spoofing SSL certificates due to incorrecting comparsion of hostnames - CAN-2004-0902: Several heap based buffer overflows in Mozilla Browsers. - CAN-2004-0903: Stack-based buffer overflow in the writeGroup function in vcard handling. - CAN-2004-0904: Overflow in BMP bitmap decoding. - CAN-2004-0905: Crossdomain scripting and possible code execution by java script  drag and drop. - CAN-2004-0906: XPI Installer sets insecure permissions, allowing local users to overwrite files of the user. - CAN-2004-0908: Allow untrusted java script  code to read and write to the clipboard. - CAN-2004-0909: Allow remote attackers to trick the user into performing dangerous operations by modifying security relevant dialog boxes. 2) solution/workaround Since there is no workaround, we recommend an update in any case if you use the mozilla browser. 3) special instructions and notes After successfully updating the package(s) you need to close all instances of the web browser and restart it again. 4) package location and checksums Due to the large amount of updated packages and dependencies we do not provide MD5-sums this time. The updates are cryptographically signed and are available for download via the Yast Online Update. ______________________________________________________________________________ 5) Pending vulnerabilities in SUSE Distributions and Workarounds: - openmotif The XPM security problems within openmotif have been fixed. New packages are available on our ftp servers. ______________________________________________________________________________ 6) standard appendix: authenticity verification, additional information - Package authenticity verification: SUSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SUSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key, the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an un-installed rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SUSE in rpm packages for SUSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SUSE Linux distributions version 7.1 and thereafter install the key "" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the top-level directory of the first CD (pubring.gpg) and at . - SUSE runs two security mailing lists to which any interested party may subscribe: - general/linux/SUSE security discussion.
