Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-1023 advisory.

- Race condition in the ath_tx_aggr_sleep function in drivers/net/wireless/ath/ath9k/xmit.c in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via a large amount of network traffic that triggers certain list deletions. (CVE-2014-2672)

- Race condition in the mac80211 subsystem in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via network traffic that improperly interacts with the WLAN_STA_PS_STA state (aka power-save mode), related to sta_info.c and tx.c. (CVE-2014-2706)

- The Netlink implementation in the Linux kernel through 3.14.1 does not provide a mechanism for authorizing socket operations based on the opener of a socket, which allows local users to bypass intended access restrictions and modify network configurations by using a Netlink socket for the (1) stdout or (2) stderr of a setuid program. (CVE-2014-0181)

- The arch_dup_task_struct function in the Transactional Memory (TM) implementation in arch/powerpc/kernel/process.c in the Linux kernel before 3.13.7 on the powerpc platform does not properly interact with the clone and fork system calls, which allows local users to cause a denial of service (Program Check and system crash) via certain instructions that are executed with the processor in the Transactional state. (CVE-2014-2673)

- arch/s390/kernel/ptrace.c in the Linux kernel before 3.15.8 on the s390 platform does not properly restrict address-space control operations in PTRACE_POKEUSR_AREA requests, which allows local users to obtain read and write access to kernel memory locations, and consequently gain privileges, via a crafted application that makes a ptrace system call. (CVE-2014-3534)

- The sctp_association_free function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not properly manage a certain backlog value, which allows remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet. (CVE-2014-4667)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
