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:
- mremap() local vulnerability (CAN-2003-0985[2]) Paul Starzetz
<ihaquer@isec.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). - Information leak in RTC code (CAN-2003-0984[3]) Russell King
<rmk@arm.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].

CONECTIVA LINUX SECURITY ANNOUNCEMENT
| PACKAGE | : | lftp |
| SUMMARY | : | Buffer overflow vulnerability |
| DATE | : | 2004-01-06 09:46:00 |
| ID | : | CLA-2004:800 |
| RELEVANT RELEASES | : | 8, 9 |
DESCRIPTION
lftp[1] is a command-line file transfer program which supports many
protocols.
Ulf Härnhammar reported[2] two buffer overflow
vulnerabilities[3] in the lftp program. An attacker could prepare a
directory on a server which, if accessed with a vulnerable lftp
with the “ls” or “rels” command, could cause arbitrary code to be
executed on the client.
SOLUTION
It is recommended that all lftp users upgrade their packages.
