CentOS Update for kernel CESA-2010:0504 centos5 i386

Published: 2011-08-09 06:20:34
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:

The remote host is missing an update for the 'kernel' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
kernel on CentOS 5

Technical Details:
The kernel Linux Distribution Packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * multiple flaws were found in the mmap and mremap implementations. A local user could use these flaws to cause a local denial of service or escalate their privileges. (CVE-2010-0291, Important) * a NULL pointer dereference flaw was found in the Fast Userspace Mutexes (futexes) implementation. The unlock code path did not check if the futex value associated with pi_state->owner had been modified. A local user could use this flaw to modify the futex value, possibly leading to a denial of service or privilege escalation when the pi_state->owner pointer is dereferenced. (CVE-2010-0622, Important) * a NULL pointer dereference flaw was found in the Linux kernel Network File System (NFS) implementation. A local user on a system that has an NFS-mounted file system could use this flaw to cause a denial of service or escalate their privileges on that system. (CVE-2010-1087, Important) * a flaw was found in the sctp_process_unk_param() function in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation. A remote attacker could send a specially-crafted SCTP packet to an SCTP listening port on a target system, causing a kernel panic (denial of service). (CVE-2010-1173, Important) * a flaw was found in the Linux kernel Transparent Inter-Process Communication protocol (TIPC) implementation. If a client application, on a local system where the tipc module is not yet in network mode, attempted to send a message to a remote TIPC node, it would dereference a NULL pointer on the local system, causing a kernel panic (denial of service). (CVE-2010-1187, Important) * a buffer overflow flaw was found in the Linux kernel Global File System 2 (GFS2) implementation. In certain cases, a quota could be written past the end of a memory page, causing memory corruption, leaving the quota stored on disk in an invalid state. A user with write access to a GFS2 file system could trigger this flaw to cause a kernel crash (denial of service) or escalate their privileges on the GFS2 server. This issue can only be triggered if the GFS2 file system is mounted with the 'quota=on' or 'quota=account' mount option. (CVE-2010-1436, Important) * a race condition between finding a keyring by name and destroying a freed keyring was found in the Linux kernel key management facility. A local user could use this flaw to cause a kernel panic (denial of service) or escalate ... Description truncated, please see the referenced URL(s) for more information.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
