Message-Id: <E1KvKHd-0000YX-1S@titan.mandriva.com> Date: Wed, 29 Oct 2008 17:17:00 -0600 From: security@...driva.com To: full-disclosure@...ts.grok.org.uk Subject: [ MDVSA-2008:220 ] kernel -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ 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.
