Mandriva Linux Security Advisory : kernel (MDVSA-2010:066)
Critical Nessus Plugin ID 48176
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionSome vulnerabilities were discovered and corrected in the Linux 2.6 kernel :
The gfs2_lock function in the Linux kernel before 2.6.34-rc1-next-20100312, and the gfs_lock function in the Linux kernel on Red Hat Enterprise Linux (RHEL) 5 and 6, does not properly remove POSIX locks on files that are setgid without group-execute permission, which allows local users to cause a denial of service (BUG and system crash) by locking a file on a (1) GFS or (2) GFS2 filesystem, and then changing this file's permissions. (CVE-2010-0727)
The do_pages_move function in mm/migrate.c in the Linux kernel before 2.6.33-rc7 does not validate node values, which allows local users to read arbitrary kernel memory locations, cause a denial of service (OOPS), and possibly have unspecified other impact by specifying a node that is not part of the kernel's node set. (CVE-2010-0415)
drivers/net/e1000e/netdev.c in the e1000e driver in the Linux kernel 22.214.171.124 and earlier does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to have an unspecified impact via crafted packets, a related issue to CVE-2009-4537. (CVE-2009-4538)
The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel before 126.96.36.199 on the x86_64 platform does not ensure that the ELF interpreter is available before a call to the SET_PERSONALITY macro, which allows local users to cause a denial of service (system crash) via a 32-bit application that attempts to execute a 64-bit application and then triggers a segmentation fault, as demonstrated by amd64_killer, related to the flush_old_exec function. (CVE-2010-0307)
Aditionally, it was added support for some backlight models used in Samsung laptops and fixes to detect Saitek X52 joysticks.
