CentOS Errata and Security Advisory CESA-2015:1137
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
It was found that the Linux kernel’s implementation of vectored pipe read
and write functionality did not take into account the I/O vectors that were
already processed when retrying after a failed atomic access operation,
potentially resulting in memory corruption due to an I/O vector array
overrun. A local, unprivileged user could use this flaw to crash the system
or, potentially, escalate their privileges on the system. (CVE-2015-1805,
Important)
A race condition flaw was found in the way the Linux kernel keys
management subsystem performed key garbage collection. A local attacker
could attempt accessing a key while it was being garbage collected, which
would cause the system to crash. (CVE-2014-9529, Moderate)
A flaw was found in the way the Linux kernel’s 32-bit emulation
implementation handled forking or closing of a task with an ‘int80’ entry.
A local user could potentially use this flaw to escalate their privileges
on the system. (CVE-2015-2830, Low)
It was found that the Linux kernel’s ISO file system implementation did
not correctly limit the traversal of Rock Ridge extension Continuation
Entries (CE). An attacker with physical access to the system could use this
flaw to trigger an infinite loop in the kernel, resulting in a denial of
service. (CVE-2014-9420, Low)
An information leak flaw was found in the way the Linux kernel’s ISO9660
file system implementation accessed data on an ISO9660 image with RockRidge
Extension Reference (ER) records. An attacker with physical access to the
system could use this flaw to disclose up to 255 bytes of kernel memory.
(CVE-2014-9584, Low)
A flaw was found in the way the nft_flush_table() function of the Linux
kernel’s netfilter tables implementation flushed rules that were
referencing deleted chains. A local user who has the CAP_NET_ADMIN
capability could use this flaw to crash the system. (CVE-2015-1573, Low)
An integer overflow flaw was found in the way the Linux kernel randomized
the stack for processes on certain 64-bit architecture systems, such as
x86-64, causing the stack entropy to be reduced by four. (CVE-2015-1593,
Low)
Red Hat would like to thank Carl Henrik Lunde for reporting CVE-2014-9420
and CVE-2014-9584. The security impact of the CVE-2015-1805 issue was
discovered by Red Hat.
This update also fixes several bugs. Documentation for these changes is
available from the following Knowledgebase article:
https://access.redhat.com/articles/1469163
All kernel users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. The system must be
rebooted for this update to take effect.
