- CVEs with nessus.description==The kernel packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issues :
- A buffer overflow flaw was found in the way the Linux
kernel's XFS file system implementation handled links
with overly long path names. A local, unprivileged user
could use this flaw to cause a denial of service or
escalate their privileges by mounting a specially
crafted disk. (CVE-2011-4077, Important)
- The fix for CVE-2011-2482 provided by a previous update
introduced a regression: on systems that do not have
Security-Enhanced Linux (SELinux) in Enforcing mode, a
socket lock race could occur between sctp_rcv() and
sctp_accept(). A remote attacker could use this flaw to
cause a denial of service. By default, SELinux runs in
Enforcing mode on Scientific Linux 5. (CVE-2011-4348,
Important)
- The proc file system could allow a local, unprivileged
user to obtain sensitive information or possibly cause
integrity issues. (CVE-2011-1020, Moderate)
- A missing validation flaw was found in the Linux
kernel's m_stop() implementation. A local, unprivileged
user could use this flaw to trigger a denial of service.
(CVE-2011-3637, Moderate)
- A flaw was found in the Linux kernel's Journaling Block
Device (JBD). A local attacker could use this flaw to
crash the system by mounting a specially crafted ext3 or
ext4 disk. (CVE-2011-4132, Moderate)
- A flaw was found in the Linux kernel's
encode_share_access() implementation. A local,
unprivileged user could use this flaw to trigger a
denial of service by creating a regular file on an NFSv4
(Network File System version 4) file system via mknod().
(CVE-2011-4324, Moderate)
- A flaw was found in the Linux kernel's NFS
implementation. A local, unprivileged user could use
this flaw to cause a denial of service. (CVE-2011-4325,
Moderate)
- A missing boundary check was found in the Linux kernel's
HFS file system implementation. A local attacker could
use this flaw to cause a denial of service or escalate
their privileges by mounting a specially crafted disk.
(CVE-2011-4330, Moderate)
This update also fixes several bugs and adds one enhancement.
Users should upgrade to these updated packages, which contain
backported patches to correct these issues, and fix the bugs and add
the enhancement noted in the Technical Notes. The system must be
rebooted for this update to take effect.
