Mandriva Linux Security Advisory MDVSA-2008:220

Package : kernel
Date : October 29, 2008
Affected: Corporate 4.0
_______________________________________________________________________

Problem Description:

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

The snd_seq_oss_synth_make_info function in
sound/core/seq/oss/seq_oss_synth.c in the sound subsystem in the Linux
kernel before 2.6.27-rc2 does not verify that the device number is
within the range defined by max_synthdev before returning certain
data to the caller, which allows local users to obtain sensitive
information. (CVE-2008-3272)

Unspecified vulnerability in the 32-bit and 64-bit emulation in the
Linux kernel 2.6.9, 2.6.18, and probably other versions allows local
users to read uninitialized memory via unknown vectors involving a
crafted binary. (CVE-2008-0598)

The (1) real_lookup and (2) __lookup_hash functions in fs/namei.c
in the vfs implementation in the Linux kernel before 2.6.25.15 does
not prevent creation of a child dentry for a deleted (aka S_DEAD)
directory, which allows local users to cause a denial of service
(overflow of the UBIFS orphan area) via a series of attempted file
creations within deleted directories. (CVE-2008-3275)

Integer overflow in the sctp_setsockopt_auth_key function in
net/sctp/socket.c in the Stream Control Transmission Protocol (sctp)
implementation in the Linux kernel 2.6.24-rc1 through 2.6.26.3 allows
remote attackers to cause a denial of service (panic) or possibly have
unspecified other impact via a crafted sca_keylength field associated
with the SCTP_AUTH_KEY option. (CVE-2008-3525)

fs/direct-io.c in the dio subsystem in the Linux kernel before 2.6.23
does not properly zero out the dio struct, which allows local users
to cause a denial of service (OOPS), as demonstrated by a certain
fio test. (CVE-2007-6716)

fs/open.c in the Linux kernel before 2.6.22 does not properly strip
setuid and setgid bits when there is a write to a file, which allows
local users to gain the privileges of a different group, and obtain
sensitive information or possibly have unspecified other impact,
by creating an executable file in a setgid directory through the (1)
truncate or (2) ftruncate function in conjunction with memory-mapped
I/O. (CVE-2008-4210)

Additionaly, support for Intel's ICH9 controller was added, and
'tg3'
driver was updated to version 3.71b.
