Date: Mon, 5 Jan 2004 13:46:45 -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-2004:799] Conectiva Security Announcement - kernel -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : kernel SUMMARY : Fix for two vulnerabilities DATE : 2004-01-05 13:46:00 ID : CLA-2004:799 RELEVANT RELEASES : 8, 9 - ------------------------------------------------------------------------- DESCRIPTION The Linux kernel is responsible for handling the basic functions of the GNU/Linux operating system. This announcement fixes two local vulnerabilities in the kernel package: 1) mremap() local vulnerability (CAN-2003-0985[2]) Paul Starzetz <ihaquer@...c.pl> from iSEC Security Research reported[1] another vulnerability in the Linux memory management code which can be used by local attackers to obtain root privileges or cause a denial of service condition (DoS). 2) Information leak in RTC code (CAN-2003-0984[3]) Russell King <rmk@....linux.org.uk> reported that real time clock (RTC) routines in Linux kernel 2.4.23 and earlier do not properly initialize their structures, which could leak kernel data to user space. SOLUTION It is recommended that all Conectiva Linux users upgrade the kernel package. 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[4].
