...tself is a very powerful attack vector. It will simplify any attack on any binary that is affected. Read the article and weep. (The ridiculous value of that kernel parameter is making matters even worse, but I understand I'll have to take up that issue elsewhere.) We do not need the privilege escalation in the binary. The vector will make any attack way easier, including a potential privilege escalation. So by continuing to have these memory leaks in the binary you are making it easier for a malevolent local user to mount an attack that might cause the "desired" privilege escalation...

Suppose the adversary is aware of a root exploit/privilege escalation in a random library.

Source: xen Version: 4.1.2-2 Severity: critical Tags: security Justification: allows PV domains to escape into the dom0 context Hi, I realize you're most likely pretty well aware of that problem already, but Debian's Xen versions are vulnerable to a PV privilege escalation [1]. The issue is tracked as CVE-2012-0217 and public as of today. Therefore I am filing this bug for coordination and traceability. Please update the packages and consider a security update for Squeeze.

I'm really struggling to explain this more simply and clearly. Privilege escalation means that the attacker gains a privilege they do not start with. Right? Escalation means that you end with more than you started with. If a local user runs pkcheck in a manner that triggers the fl...

hey.. I talked to my sysadmins about getting access to the dtrace_kernel role, and they said they were hesitant to give this out because they thought it was a security risk - ie: that you could use it for privilege escalation. How true is this? Is there a way to make it user safe? If not, why is it offered as an option for regular users? Thanks much, Ed -- This message posted from opensolaris.org

Howdy, have working realtime queues using queue_members looking something like; queuea|Local/101@context|0 queuea|Local/102@context|1 queuea|Local/103@context|10 Regardless of what strategy is used in the queues (roundrobin,rrmemory,ringall etc) it wont escalate on NOANSWER Asterisk SVN-branch-1.2-r33841 Any clues are appreciated! /Danny

...ait for the official kernel. It is the standard CentOS kernel with one added patch ( https://bugzilla.redhat.com/attachment.cgi?id=767364) This kernel needs to be tested for fitness by each user before being placed in production. It is a best effort to mitigate an issue that can cause local user escalation to root while waiting for upstream to fix and QA the official kernel. Use at your own risk.
