Mandrake 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.

 Mandriva Linux Security Advisory                         MDVSA-2008:220
 http://www.mandriva.com/security/
 _______________________________________________________________________

 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.
