Mandriva Linux Security Advisory : kernel (MDVSA-2009:119)

This script is Copyright (C) 2010-2016 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Some vulnerabilities were discovered and corrected in the Linux 2.6
kernel :

The exit_notify function in kernel/exit.c in the Linux kernel before
2.6.30-rc1 does not restrict exit signals when the CAP_KILL capability
is held, which allows local users to send an arbitrary signal to a
process by running a program that modifies the exit_signal field and
then uses an exec system call to launch a setuid application.
(CVE-2009-1337)

The selinux_ip_postroute_iptables_compat function in
security/selinux/hooks.c in the SELinux subsystem in the Linux kernel
before 2.6.27.22, and 2.6.28.x before 2.6.28.10, when compat_net is
enabled, omits calls to avc_has_perm for the (1) node and (2) port,
which allows local users to bypass intended restrictions on network
traffic. NOTE: this was incorrectly reported as an issue fixed in
2.6.27.21. (CVE-2009-1184)

drivers/char/agp/generic.c in the agp subsystem in the Linux kernel
before 2.6.30-rc3 does not zero out pages that may later be available
to a user-space process, which allows local users to obtain sensitive
information by reading these pages. (CVE-2009-1192)

Integer overflow in rose_sendmsg (sys/net/af_rose.c) in the Linux
kernel 2.6.24.4, and other versions before 2.6.30-rc1, might allow
remote attackers to obtain sensitive information via a large length
value, which causes garbage memory to be sent. (CVE-2009-1265)

To update your kernel, please follow the directions located at :
