"The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2009-1243 advisory.
- The ext4_group_add function in fs/ext4/resize.c in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28
before 2.6.28.7 does not properly initialize the group descriptor during a resize (aka resize2fs)
operation, which might allow local users to cause a denial of service (OOPS) by arranging for crafted
values to be present in available memory. (CVE-2009-0745)
- The make_indexed_dir function in fs/ext4/namei.c in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28
before 2.6.28.7 does not validate a certain rec_len field, which allows local users to cause a denial of
service (OOPS) by attempting to mount a crafted ext4 filesystem. (CVE-2009-0746)
- The ext4_isize function in fs/ext4/ext4.h in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before
2.6.28.7 uses the i_size_high structure member during operations on arbitrary types of files, which allows
local users to cause a denial of service (CPU consumption and error-message flood) by attempting to mount
a crafted ext4 filesystem. (CVE-2009-0747)
- The ext4_fill_super function in fs/ext4/super.c in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28
before 2.6.28.7 does not validate the superblock configuration, which allows local users to cause a denial
of service (NULL pointer dereference and OOPS) by attempting to mount a crafted ext4 filesystem.
(CVE-2009-0748)
- The do_sigaltstack function in kernel/signal.c in Linux kernel 2.4 through 2.4.37 and 2.6 before
2.6.31-rc5, when running on 64-bit systems, does not clear certain padding bytes from a structure, which
allows local users to obtain sensitive information from the kernel stack via the sigaltstack function.
(CVE-2009-2847)
- The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the
current->clear_child_tid pointer, which allows local users to cause a denial of service (memory
corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or
CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.
(CVE-2009-2848)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
