-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: lynx-2.8.2 and older Date: Thu Sep 16 21:29:15 CEST 1999 Affected: all Linux distributions using lynx-2.8.2 and older ______________________________________________________________________________ A security hole was discovered in the package mentioned above. Please update as soon as possible or disable the service if you are using this software on your SuSE Linux installation(s). Other Linux distributions or operating systems might be affected as well, please contact your vendor for information about this issue. Please note, that that we provide this information on as "as-is" basis only. There is no warranty whatsoever and no liability for any direct, indirect or incidental damage arising from this information or the installation of the update package. _____________________________________________________________________________ 1. Problem Description When lynx calls external programs for protocols (e.g. telnet), the location is passed unchecked. This can be used to activate commandline parameters. For example, this reference [A HREF="telnet://-n.rhosts"]click me[/A] would activate the tracefile options on the telnet client, with the result, that a .rhosts in the current directory would created or overwritten. 2. Impact Depending on the external programs called by lynx, files can be created or truncated, or even remote commands being executed if e.g. ssh or rsh would be configured in lynx. 3. Solution Updated the lynx package from our FTP server. ______________________________________________________________________________ Here are the md5 checksums of the upgrade packages, please verify these before installing the new packages: lynx-2.8.3dev9-76.i386.rpm fd29230757f76d33e21836965822f7a6 (5.3) lynx-2.8.3dev9-76.i386.rpm 2fba1f9fcf2c3ad9bbb23f0ea18acecd (6.0) lynx-2.8.3dev9-76.alpha.rpm f706fa71b38721d1d0e1e69700c467a4 (AXP) lynx-2.8.3dev9-76.i386.rpm 2fba1f9fcf2c3ad9bbb23f0ea18acecd (6.1) lynx-2.8.3dev9-76.i386.rpm 18f870d15016f63aa510cc5161c027c2 (6.2) ______________________________________________________________________________ You will find the update on our ftp-Server: ftp://ftp.suse.com/pub/suse/i386/update/5.3/n1/lynx-2.8.3dev9-76.i386.rpm ftp://ftp.suse.com/pub/suse/axp/update/6.1/n1/lynx-2.8.3dev9-76.alpha.rpm ftp://ftp.suse.com/pub/suse/i386/update/6.1/n1/lynx-2.8.3dev9-76.i386.rpm ftp://ftp.suse.com/pub/suse/i386/update/6.2/n1/lynx-2.8.3dev9-76.i386.rpm Webpage for patches: http://www.suse.de/patches/index.html or try the following web pages for a list of mirrors: http://www.suse.de/ftp.html http://www.suse.com/ftp_new.html ______________________________________________________________________________ SuSE has got two free security mailing list services to which any interested party may subscribe: use-security@suse.com - moderated and for general/linux/SuSE security discussions.
