Ubuntu 8.10 : linux regression (USN-661-1)

Version 2.6.27 of the Linux kernel changed the order of options in TCP headers. While this change was RFC-compliant, it was found that some old routers and consumer DSL modems would not route traffic for these systems when TCP timestamps were enabled. As a workaround, TCP timestamps were disabled...

SuSE 10 Security Update : Linux kernel (ZYPP Patch Number 4935)

This kernel update fixes the following security problems : - Insufficient range checks in certain fault handlers could be used by local attackers to potentially read or write kernel memory. CVE-2008-0007 - Incorrect access mode checks could be used by local attackers to corrupt directory contents...

FreeBSD -- Jail rc.d script privilege escalation

Problem Description: In multiple situations the host's jail rc.d8 script does not check if a path inside the jail file system structure is a symbolic link before using the path. In particular this is the case when writing the output from the jail start-up to /var/log/console.log and when mounting...
