re: x carlo
carlo senza polemiche ci mancherebbe altro ma mi stavo guardando gli exploit di cui la attuale debian è affetta e ti giuro non me ricordavo così tanti guarda:
Date Reported:
09 Apr 2001
Affected Packages:
ntpd
Vulnerable:
Yes
More information:
Przemyslaw Frasunek <venglin@FREEBSD.LUBLIN.PL> reported that ntp daemons such as that released with Debian GNU/Linux are vulnerable to a buffer overflow that can lead to a remote root exploit. A previous advisory (DSA-045-1) partially addressed this issue, but introduced a potential denial of service attack. This has been corrected for Debian 2.2 (potato) in ntp version 4.0.99g-2potato2.
Date Reported:
09 Mar 2001
Affected Packages:
zope
Vulnerable:
Yes
More information:
This advisory covers several vulnerabilities in Zope that have been addressed.
Hotfix 08_09_2000 "Zope security alert and hotfix product"
The issue involves the fact that the getRoles method of user objects contained in the default UserFolder implementation returns a mutable Python type. Because the mutable object is still associated with the persistent User object, users with the ability to edit DTML could arrange to give themselves extra roles for the duration of a single request by mutating the roles list as a part of the request processing.
Hotfix 2000-10-02 "ZPublisher security update"
It is sometimes possible to access, through an URL only, objects protected by a role which the user has in some context, but not in the context of the accessed object.
Hotfix 2000-10-11 "ObjectManager subscripting"
The issue involves the fact that the 'subscript notation' that can be used to access items of ObjectManagers (Folders) did not correctly restrict return values to only actual sub items. This made it possible to access names that should be private from DTML (objects with names beginning with the underscore '_' character). This could allow DTML authors to see private implementation data structures and in certain cases possibly call methods that they shouldn't have access to from DTML.
Hotfix 2001-02-23 "Class attribute access"
The issue is related to ZClasses in that a user with through-the-web scripting capabilities on a Zope site can view and assign class attributes to ZClasses, possibly allowing them to make inappropriate changes to ZClass instances.
A second part fixes problems in the ObjectManager, PropertyManager, and PropertySheet classes related to mutability of method return values which could be perceived as a security problem.
These fixes are included in zope 2.1.6-7 for Debian 2.2 (potato). We recommend you upgrade your zope package immediately.
Date Reported:
07 Mar 2001
Affected Packages:
eperl
Vulnerable:
Yes
More information:
Fumitoshi Ukai and Denis Barbier have found several potential buffer overflow bugs in our version of ePerl as distributed in all of our distributions.
When eperl is installed setuid root, it can switch to the UID/GID of the scripts owner. Although Debian doesn't ship the program setuid root, this is a useful feature which people may have activated locally. When the program is used as /usr/lib/cgi-bin/nph-eperl the bugs could lead into a remote vulnerability as well.
Version 2.2.14-0.7potato2 fixes this; we recommend you upgrade your eperl package immediately.
Date Reported:
09 Feb 2001
Affected Packages:
ssh
Vulnerable:
Yes
More information:
Versions of OpenSSH prior to 2.3.0 are vulnerable to a remote arbitrary memory overwrite attack which may lead to a root exploit.
CORE-SDI has described a problem with regards to RSA key exchange and a Bleichenbacher attack to gather the session key from an ssh session.
Both of these issues have been corrected in our ssh package 1.2.3-9.2. We recommend you upgrade your openssh package immediately.
Date Reported:
23 Jan 2001
Affected Packages:
tinyproxy
Vulnerable:
Yes
More information:
PkC have found a heap overflow in tinyproxy that could be remotely exploited. An attacker could gain a shell (user nobody) remotely.
We recommend you upgrade your tinyproxy package immediately.
Date Reported:
22 Jan 2001
Affected Packages:
micq
Vulnerable:
Yes
More information:
PkC has reported that there is a buffer overflow in sprintf() in micq versions 0.4.6 and previous, that allows to a remote attacker able to sniff packets to the ICQ server to execute arbitrary code on the victim system.
We recommend you upgrade your micq package immediately.
come premettevo l'aggiornamento dei pacchetti è fondamentale a dopo
