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.
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)
Intel i386 Platform
2) Pending vulnerabilities in SuSE Distributions and Workarounds:
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.
The in.identd daemon on SuSE distributions can be crashed remotely. We're working on a fix.
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).
The paragraph above about bash version 1 applies to the tcsh as well, in all versions. The tcsh is not used by SuSE scripts.
3) standard appendix:
