Mandrake Linux Security Advisory : kernel (MDKSA-2007:078)

Synopsis :

The remote Mandrake Linux host is missing one or more security

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 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 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.

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.
