 _______________________________________________________________________   Mandriva Linux Security Advisory                        MDVSA-2008:105  http://www.mandriva.com/security/  _______________________________________________________________________   Package : kernel  Date   : May 21, 2008  Affected: 2007.1  _______________________________________________________________________   Problem Description:   The CIFS filesystem in the Linux kernel before 2.6.22, when Unix extension support is enabled, does not honor the umask of a process, which allows local users to gain privileges. (CVE-2007-3740)   The drm/i915 component in the Linux kernel before 2.6.22.2, when used with i965G and later chipsets, allows local users with access to an X11 session and Direct Rendering Manager (DRM) to write to arbitrary memory locations and gain privileges via a crafted batchbuffer. (CVE-2007-3851)   The (1) hugetlb_vmtruncate_list and (2) hugetlb_vmtruncate functions in fs/hugetlbfs/inode.c in the Linux kernel before 2.6.19-rc4 perform certain prio_tree calculations using HPAGE_SIZE instead of PAGE_SIZE units, which allows local users to cause a denial of service (panic) via unspecified vectors. (CVE-2007-4133)   The IA32 system call emulation functionality in Linux kernel 2.4.x and 2.6.x before 2.6.22.7, when running on the x86_64 architecture, does not zero extend the eax register after the 32bit entry path to ptrace is used, which might allow local users to gain privileges by triggering an out-of-bounds access to the system call table using the %RAX register. This vulnerability is now being fixed in the Xen kernel too. (CVE-2007-4573)   Integer underflow in the ieee80211_rx function in net/ieee80211/ieee80211_rx.c in the Linux kernel 2.6.x before  2.6.23 allows remote attackers to cause a denial of service (crash) via a crafted SKB length value in a runt IEEE 802.11 frame when the IEEE80211_STYPE_QOS_DATA flag is set, aka an off-by-two error. (CVE-2007-4997)   The disconnect method in the Philips USB Webcam (pwc) driver in Linux kernel 2.6.x before 2.6.22.6 relies on user space to close the device, which allows user-assisted local attackers to cause a denial of service (USB subsystem hang and CPU consumption in khubd) by not closing the device after the disconnect is invoked. NOTE: this rarely crosses privilege boundaries, unless the attacker can convince the victim to unplug the affected device. (CVE-2007-5093)   A race condition in the directory notification subsystem (dnotify) in Linux kernel 2.6.x before 2.6.24.6, and 2.6.25 before 2.6.25.1, allows local users to cause a denial of service (OOPS) and possibly gain privileges via unspecified vectors. (CVE-2008-1375)   The Linux kernel before 2.6.25.2 does not apply a certain protection mechanism for fcntl functionality, which allows local users to (1) execute code in parallel or (2) exploit a race condition to obtain re-ordered access to the descriptor table. (CVE-2008-1669)   To update your kernel, please follow the directions located at:    http://www.mandriva.com/en/security/kernelupdate  _______________________________________________________________________  References:   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3740  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3851  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4133  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4573  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4997  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5093  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1375  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1669  _______________________________________________________________________ Updated Packages:   Mandriva Linux 2007.1:  c4a2d4a2c510a0b264ecc556ae95d9c1 2007.1/i586/kernel-2.6.17.18mdv-1-1mdv2007.1.i586.rpm  8a9067dced69f2a98d84a91b565d53b2 2007.1/i586/kernel-doc-2.6.17.18mdv-1-1mdv2007.1.i586.rpm  3781406fba53b54e10f10c673ad54734 2007.1/i586/kernel-doc-latest-2.6.17-18mdv.i586.rpm  0ab62eecb317efb9f395067acff4f197 2007.1/i586/kernel-enterprise-2.6.17.18mdv-1-1mdv2007.1.i586.rpm  fa94fc4948555ddae5f333e51c1edac5 2007.1/i586/kernel-enterprise-latest-2.6.17-18mdv.i586.rpm  0997abceef3793c25a8fa5fee56af005 2007.1/i586/kernel-latest-2.6.17-18mdv.i586.rpm  02b79be3ea9a145e8e264e2f104c27fb 2007.1/i586/kernel-legacy-2.6.17.18mdv-1-1mdv2007.1.i586.rpm  53e8e4e029f99fede270f4a4e9b1f105 2007.1/i586/kernel-legacy-latest-2.6.17-18mdv.i586.rpm  b38fcb899cd7e473bd07ab296a0edc52 2007.1/i586/kernel-source-2.6.17.18mdv-1-1mdv2007.1.i586.rpm  df638346ea8e84c542b5d54173ef40f7 2007.1/i586/kernel-source-latest-2.6.17-18mdv.i586.rpm  5749113a50606c4f81f1371150c59041 2007.1/i586/kernel-source-stripped-2.6.17.18mdv-1-1mdv2007.1.i586.rpm  bb3e5dddd12bfc05809a83f9c5e5a568 2007.1/i586/kernel-source-stripped-latest-2.6.17-18mdv.i586.rpm  4d4708a7c62727c704db6fa7a244d426 2007.1/i586/kernel-xen0-2.6.17.18mdv-1-1mdv2007.1.i586.rpm  44b7732796ed652fc66034a2e1983f29 2007.1/i586/kernel-xen0-latest-2.6.17-18mdv.i586.rpm  1d6b03aad48cbe295ad461605d234eac 2007.1/i586/kernel-xenU-2.6.17.18mdv-1-1mdv2007.1.i586.rpm  af2a8a7596097a04a22292686da8471f 2007.1/i586/kernel-xenU-latest-2.6.17-18mdv.i586.rpm  327a8315418ff84959418928fc9873a5 2007.1/SRPMS/kernel-2.6.17.18mdv-1-1mdv2007.1.src.rpm  Mandriva Linux 2007.1/X86_64:  4b114a0b6712df7b93582805489a0e18 2007.1/x86_64/kernel-2.6.17.18mdv-1-1mdv2007.1.x86_64.rpm  fb4214952ca5cc240adaeec74e377181 2007.1/x86_64/kernel-doc-2.6.17.18mdv-1-1mdv2007.1.x86_64.rpm  30744081c4e43f608359eea6e201a4cd 2007.1/x86_64/kernel-doc-latest-2.6.17-18mdv.x86_64.rpm  0e8a29bbe26469de5ec6e9ec44b02c13 2007.1/x86_64/kernel-latest-2.6.17-18mdv.x86_64.rpm  1f3a2aa6965565c2db3bb5ca823fb546 2007.1/x86_64/kernel-source-2.6.17.18mdv-1-1mdv2007.1.x86_64.rpm  7f3564691ddacf4e8a7d4ce874b8a33e 2007.1/x86_64/kernel-source-latest-2.6.17-18mdv.x86_64.rpm  fe9ecda0a6ea8a0723898ccda5292bc8 2007.1/x86_64/kernel-source-stripped-2.6.17.18mdv-1-1mdv2007.1.x86_64.rpm  f7c9adbabba9b8a56fec55715a1e4858 2007.1/x86_64/kernel-source-stripped-latest-2.6.17-18mdv.x86_64.rpm  3e9422670548692022834ac806204fb8 2007.1/x86_64/kernel-xen0-2.6.17.18mdv-1-1mdv2007.1.x86_64.rpm  2c18b8148db64d58d2a076b0b0b13d21 2007.1/x86_64/kernel-xen0-latest-2.6.17-18mdv.x86_64.rpm  10f28963d97d785b4bbea94610e4d478 2007.1/x86_64/kernel-xenU-2.6.17.18mdv-1-1mdv2007.1.x86_64.rpm  efa8b29e7e3d5907ccdf917514797e07 2007.1/x86_64/kernel-xenU-latest-2.6.17-18mdv.x86_64.rpm  327a8315418ff84959418928fc9873a5 2007.1/SRPMS/kernel-2.6.17.18mdv-1-1mdv2007.1.src.rpm  _______________________________________________________________________  To upgrade automatically use MandrivaUpdate or urpmi. The verification of md5 checksums and GPG signatures is performed automatically for you.  All packages are signed by Mandriva for security. You can obtain the GPG public key of the Mandriva Security Team by executing:  gpg --recv-keys --keyserver pgp.mit.edu 0x22458A98  You can view other update advisories for Mandriva Linux at:  http://www.mandriva.com/security/advisories  If you want to report vulnerabilities, please contact  security_(at)_mandriva.com  _______________________________________________________________________
