Date: Fri, 20 Feb 2004 14:49:26 -0200 From: Conectiva Updates <secure@...ectiva.com.br> To: conectiva-updates@...aleguas.conectiva.com.br, lwn@....net, bugtraq@...urityfocus.com, security-alerts@...uxsecurity.com, linsec@...ts.seifried.org Subject: [CLA-2004:820] Conectiva Security Announcement - kernel -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : kernel SUMMARY : Fixes for kernel vulnerabilities DATE : 2004-02-20 14:47:00 ID : CLA-2004:820 RELEVANT RELEASES : 8, 9 - ------------------------------------------------------------------------- DESCRIPTION The Linux kernel is responsible for handling the basic functions of the GNU/Linux operating system. Paul Starzetz <ihaquer@...c.pl> identified[1] a new vulnerability[2] in the linux memory management code that can be used by local attackers to obtain root privileges. Two other, unrelated, fixes have also been included in this update: - CAN-2004-0010[4]: vulnerability in the ncp file system (ncpfs); - local kmod denial of service (no CAN alocated to this issue)[5]. SOLUTION It is recommended that all users upgrade the kernel packages. IMPORTANT: exercise caution and preparation when upgrading the kernel, since it will require a reboot after the new packages are installed. In particular, Conectiva Linux 9 will most likely require an initrd file (which is automatically created in the /boot directory after the new packages are installed). Generic kernel update instructions can be obtained in the manuals and in our faq page[3].
