Mandriva Linux Security Advisory MDKSA-2007:078

Package : kernel
Date : April 4, 2007
Affected: 2007.0
_______________________________________________________________________

Problem Description:

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

When SELinux hooks are enabled, the kernel could allow a local user
to cause a DoS (crash) via a malformed file stream that triggers a
NULL pointer derefernece (CVE-2006-6056).

Multiple buffer overflows in the (1) read and (2) write handlers in
the Omnikey CardMan 4040 driver in the Linux kernel before 2.6.21-rc3
allow local users to gain privileges. (CVE-2007-0005)

The Linux kernel version 2.6.13 to 2.6.20.1 allowed a remote attacker to
cause a DoS (oops) via a crafted NFSACL2 ACCESS request that triggered
a free of an incorrect pointer (CVE-2007-0772).

A local user could read unreadable binaries by using the interpreter
(PT_INTERP) functionality and triggering a core dump; a variant of
CVE-2004-1073 (CVE-2007-0958).

The ipv6_getsockopt_sticky function in net/ipv6/ipv6_sockglue.c in the
Linux kernel before 2.6.20.2 allows local users to read arbitrary
kernel memory via certain getsockopt calls that trigger a NULL
dereference. (CVE-2007-1000)

Buffer overflow in the bufprint function in capiutil.c in libcapi,
as used in Linux kernel 2.6.9 to 2.6.20 and isdn4k-utils, allows local
users to cause a denial of service (crash) and possibly gain privileges
via a crafted CAPI packet. (CVE-2007-1217)

The do_ipv6_setsockopt function in net/ipv6/ipv6_sockglue.c in Linux
kernel 2.6.17, and possibly other versions, allows local users to cause
a denial of service (oops) by calling setsockopt with the IPV6_RTHDR
option name and possibly a zero option length or invalid option value,
which triggers a NULL pointer dereference. (CVE-2007-1388)

net/ipv6/tcp_ipv6.c in Linux kernel 2.4 and 2.6.x up to 2.6.21-rc3
inadvertently copies the ipv6_fl_socklist from a listening TCP socket
to child sockets, which allows local users to cause a denial of service
(OOPS) or double-free by opening a listeing IPv6 socket, attaching a
flow label, and connecting to that socket. (CVE-2007-1592)

The provided packages are patched to fix these vulnerabilities.
All users are encouraged to upgrade to these updated kernels immediately
and reboot to effect the fixes.

In addition to these security fixes, other fixes have been included
such as:

- Suspend to disk speed improvements
