Sollte man für Sicherheitslöcher nicht evtl eine eigene Rubrik eröffnen: "Patches und Workarounds". Denn ich denke, dass da doch öfters mal was kommen wird, und wenn Interesse an diesen Informationen besteht (wobei im Heimbereich diese nur von eingeschränkter Bedeutung sind, gerade was Angriffe von lokalen Benutzern angeht), dann könnte man so schneller relevante Informationen finden evtl mit Workarounds und der Möglichkeit Fragen zu stellen.

[Impact]

Hmm, jo danke für die Info, aber bei mir kommt sowieso nichts unter zzt. 6.5.19 auf die Platte
Grüsse,
Markus.

Naja,

so wenige SGI CERTs wie es gibt es es nicht unbedingt nötig.

Ich kenne 3 in den letzten 12 Monaten...

Aber evtl. wäre eine Rubrik 'News' ganz interessant, in Sonnenblen.de wird sie gerne genutzt und CERTs passen gut rein, abgesehen von anderem Content.

PS:
Da war er wiedermal zu schnell...

Es sagt keiner dass es ein Copy Past von heise geben muss - wobei heise sicher nicht der einzige gute News Lieferant ist.

Wenn die Leute hier Lust haben News zusammen zu tragen erparen sie anderen das abklappern von x Pages... meine Meinung.

[Impact]

Hmm jo ich könnte wenns was werden soll mit der neuen Rubrik immer das Aktuellste pasten, da ich immer per Mail vom SGI Security Coordinator die Security Holes in IRIX reinbekomme, weiss zwar auch nicht warum aber, naja
Würde dann in etwa so aussehen:

                         SGI Security Advisory

Title    : Buffer Overrun Vulnerability in /sbin/ps
Number   : 20030202-01-I
Date     : February 26, 2003
Reference: CVE-1999-0301
Reference: SGI BUG 696723
Fixed in : IRIX 6.5.5 or later
______________________________________________________________________________

- -----------------------
- --- Issue Specifics ---
- -----------------------

It has been reported that there was a potential buffer overrun vulnerability
in the /sbin/ps program.  This could result in a user with a local account
gaining privileged access.

For more information, see:
ftp://ftp.sco.com/pub/updates/OpenUNIX/CSSA-2003-SCO.1.1/CSSA-2003-SCO.1.1.txt
and http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-1999-0301


SGI has investigated the issue and recommends the following steps for
neutralizing the exposure.  It is HIGHLY RECOMMENDED that these measures be
implemented on ALL vulnerable SGI systems.

These issues have been corrected in IRIX 6.5.5 and later.


- --------------
- --- Impact ---
- --------------

The /sbin/ps binary is installed by default on IRIX 6.5 systems as part of
eoe.sw.base.

To determine the version of IRIX you are running, execute the following
command:

 # /bin/uname -R

That will return a result similar to the following:

 # 6.5 6.5.16f

The first number ("6.5") is the release name, the second ("6.5.16f" in this
case) is the extended release name.  The extended release name is the
"version" we refer to throughout this document.


- ----------------------------
- --- Temporary Workaround ---
- ----------------------------

There is no effective workaround available for this problem.
SGI recommends upgrading to IRIX 6.5.5 or later.


- ----------------
- --- Solution ---
- ----------------

SGI has not provided patches for this vulnerability. Our recommendation
is to upgrade to IRIX 6.5.5 or later.

Hi!

Hab das bei mir abgestellt, weil mich diese Mails nervten. IMO reichts, wenn man die entsprechenden Newsgroups ein wenig mitverfolgt. Die meisten der Patches sind eh irrlelevant.
Bei uns in der Firma gibt's auf dem Install-Server ein File, in dem alle relevanten Patches für IRIX, AIX, Catia, ... aufgeführt sind, das wird alle paar Tage aktualisiert. Hab das ständige Patchen meiner privaten Rechner schon lange aufgegeben, da kommst Du irgendwann zu nichts anderem mehr. In der Firma läuft das zum Glück zentral, bis auf ein paar Ausnahmen, wenn ein Rechner z.B. die exakt gleiche Konfiguration wie beim Kunden haben muss.

Servus,
  Michael

Nuja war ja nur ein angebot.
Und ein neuer Patchlevel kommt bei mir auch nur mit neuen Overlays zustande sonst seperat nicht.
Grüsse,
Markus
