Red Hat Linux 7.1 Advisory RHSA-2003:026-01 Critical Netscape Security Fix

Updated Netscape 4.8 packages fixing various bugs and vulnerabilities arenow available.. ` --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated Netscape packages are now available Advisory ID: RHSA-2003:026-01 Issue date: 2003-06-20 Updated on: 2003-06-20 Product: Red Hat Linux Keywords: netscape shockwave flash Cross references: Obsoletes: RHSA-2001:046 CVE Names: CVE-2002-0846 CAN-2002-1467 --------------------------------------------------------------------- 1. Topic: Updated Netscape 4.8 packages fixing various bugs and vulnerabilities are now available. 2. Relevant releases/architectures: Red Hat Linux 7.1 - i386 Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 3. Problem description: Netscape is a suite of Internet utilities including a Web browser, email client, and Usenet news reader. Netscape version 4.8 contains various bugfixes and updates. Note that Macromedia Flash is no longer included as of this update. The recommended Macromedia Flash with security fixes no longer supports Netscape 4.x. The security issues that affected the Macromedia Flash player include CVE-2002-0846 and CAN-2002-1467. It is recommended that all Netscape Communicator and Netscape Navigator users upgrade to these errata packages. 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 Red Hat Network. Many people find this an easier way to apply updates. Touse Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. Bug IDs fixed ( for more info): 62052 - Does the netscape libflashplugin.so use an insecure zlib ?? 65862 - A problem for the zh_CN.GB2312 locale 71341 - Lots of security holes in flash plugin 6.

Debian: DSA 051-1 critical: netscape javascript execution issue

Florian Wesch has discovered a problem (reported to bugtraq) with the way how Netscape handles comments in GIF files.. ---------------------------------------------------------------------------- Debian Security Advisory DSA 051-1 This email address is being protected from spambots. You need JavaScript enabled to view it. Debian -- Security Information Martin Schulze April 23, 2001 ---------------------------------------------------------------------------- Package : netscape Vulnerability : unexpected javascript execution Problem-Type : remote information gathering Debian-specific: no Florian Wesch has discovered a problem (reported to bugtraq) with the way how Netscape handles comments in GIF files. The Netscape browser does not escape the GIF file comment in the image information page. This allows javascript execution in the "about:" protocol and can for example be used to upload the History (about:global) to a webserver, thus leaking private information. This problem has been fixed upstream in Netscape 4.77. Since we haven't received sourcecode for these packages they are not part of the Debian GNU/Linux distribution but are packaged up as `.deb' files for a convenient installation. We recommend that you upgrade your Netscape packages immediately and remove older versions. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get install netscape will install the new netscape packages You may use an automated update by adding the resources from the footer to the proper configuration. Debian GNU/Linux 2.2 alias potato ------------------------------------ Potato was released for the alpha, arm, i386, m68k, powerpc and sparc architectures.

Red Hat 6.2: RHSA-2000:046-02 Critical: Netscape JPEG Overflow

New netscape packages are available that fix a potential overflow due to improper input verification in netscape's JPEGprocessing code.. ` --------------------------------------------------------------------- Red Hat, Inc. Security Advisory Synopsis: New netscape packages available to fix JPEG problem Advisory ID: RHSA-2000:046-02 Issue date: 2000-07-28 Updated on: 2000-07-28 Product: Red Hat Linux Keywords: netscpae JPEG Cross references: N/A --------------------------------------------------------------------- 1. Topic: New netscape packages are available that fix a potential overflow due to improper input verification in netscape's JPEG processing code. It is recommended that users of netscape update to the fixed packages. Users of Red Hat Linux 6.0 and 6.1 should use the packages for Red Hat Linux 6.2. 2. Relevant releases/architectures: Red Hat Linux 5.2 - i386 Red Hat Linux 6.0 - i386 Red Hat Linux 6.1 - i386 Red Hat Linux 6.2 - i386, alpha 3. Problem description: Netscape's processing of JPEG comments trusted the length parameter for comment fields; by manipulating this value, it would be possible to cause netscape to read in an excessive amount of data, overwriting memory. Specially designed data could allow a remote site to execute arbitrary code as the user of netscape. This vulnerability is fixed in Netscape 4.74. 4. Solution: For each RPM for your particular architecture, run: rpm -Fvh [filename] where filename is the name of the RPM. 5. Bug IDs fixed ( for more info): 10165 - Netscape mail client does not compact folders anymore 13695 - Small glitch in German translation 14506 - Upgrade of netscape-common fails 14657 - /usr/lib/netscape/de_DE: cpio: unlinkfailed 6.
