Advisories MDKSA-2007:078: Updated kernel packages fix multiple vulnerabilities and bugs

[paul]

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.
