SuSE Security Announcement
Package: netscape
Announcement-ID: SuSE-SA:2000:48
Date: Thursday, November 30th, 2000 19:00 MET
Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0
Vulnerability Type: clientside remote vulnerability
Severity (1-10): 4
SuSE default package: yes
Other affected systems: systems w/ netscape versions before 4.76
Content of this advisory:
1) security vulnerability resolved: netscape
problem description, discussion, solution and upgrade information
2) pending vulnerabilities, solutions, workarounds
3) standard appendix (further information)
______________________________________________________________________________
1) problem description, brief discussion, solution, upgrade
information
Michal Zalewski <lcamtuf@DIONE.IDS.PL> has found a buffer
overflow in the html parser code of the Netscape Navigator in all
versions before and including 4.75. html code of the form
<form action=foo method=bar>
<input type=password value=long string here>
more form tags
</form>
can crash the browser. It may be possible for an attacker to
supply a webpage that executes arbitrary code as the user running
netscape. As of today, no exploit code is known to exist in the
wild.
SuSE provides an update package for the vulnerable software. It
is recommended to upgrade to the latest version found on our ftp
server as described below. The update package introduces Netscape
version 4.76.
NOTE: Please note that Netscape-4.76 is not available for the
glibc-2.0-based SuSE Distributions SuSE-6.0 and 6.1 because
Netscape doesn't provide any binaries for the glibc version in
these distributions (glibc-2.0). For SuSE-6.0 and 6.1, we
provide a libc5-based version of netscape-4.76 which runs
smoothly on all i386-based SuSE distributions 6.x and 7.x,
provided the package shlibs5 is installed. The package can be
found in the update/5.3 directory on our ftp server (see below).
There are no packages available for platforms other than i386.
NOTE: The packages on our ftp servers date back to October
31st. Since there is no release notes or README file with
equivalent content in the netscape tarball, SuSE security was not
aware of the fact that this release of netscape fixes the known
problems. This information can be obtained from (along with
information about other bugfixes)
http://home.netscape.com/eng/mozilla/4.7/relnotes/windows-4.76.html
.
Please choose the update package(s) for your distribution from the URLs
listed below and download the necessary rpm files. Then, install the
package using the command `rpm -Uhv file.rpm´. rpm packages have an
internal md5 checksum that protects against file corruption. You can
verify this checksum using the command (independently from the md5
signatures below)
`rpm --checksig --nogpg file.rpm',
The md5 sums under each package are to prove the package authenticity,
independently from the md5 checksums in the rpm package format.

2) Pending vulnerabilities in SuSE Distributions and Workarounds:
- ssh/openssh
Several inconsistencies and configuration bugs have been
introduced in the SuSE rpm packages for the update of openssh
(SuSE-SA:2000:47) that cause the openssh software to not work
as reliably as usual. The packages are about to be reworked,
the openssh announcement will be reissued.
- pidentd
The in.identd daemon on SuSE distributions can be crashed
remotely. We're working on a fix.
- bash1
bash, version 1, handles temporary files in an unsafe manner
that allows a local attacker to overwrite arbitrary files as
the user running a bash1 with input redirection of the "<< EOF"
style. The bash1 package is not used per default in
SuSE-distributions. We're working on a fix (update packages).
- tcsh
The paragraph above about bash version 1 applies to the tcsh as
well, in all versions. The tcsh is not used by SuSE scripts.
