Redhat : Security Vulnerabilities, CVEs, Published In August 2015

The (1) udp_recvmsg and (2) udpv6_recvmsg functions in the Linux kernel before 4.0.6 provide inappropriate -EAGAIN return values, which allows remote attackers to cause a denial of service (EPOLLET epoll application read outage) via an incorrect checksum in a UDP packet, a different vulnerability than CVE-2015-5364.

The (1) udp_recvmsg and (2) udpv6_recvmsg functions in the Linux kernel before 4.0.6 do not properly consider yielding a processor, which allows remote attackers to cause a denial of service (system hang) via incorrect checksums within a UDP packet flood.

Red Hat OpenShift Enterprise 3.0.0.0 does not properly check permissions, which allows remote authenticated users with build permissions to execute arbitrary shell commands with root permissions on arbitrary build pods via unspecified vectors.

The PortletRequestDispatcher in PortletBridge, as used in Red Hat JBoss Portal 6.2.0, does not properly enforce the security constraints of servlets, which allows remote attackers to gain access to resources via a request that asks to render a non-JSF resource.

The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors.

arch/x86/entry/entry_64.S in the Linux kernel before 4.1.6 on the x86_64 platform mishandles IRET faults in processing NMIs that occurred during userspace execution, which might allow local users to gain privileges by triggering an NMI.

Ansible before 1.9.2 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

The ping_unhash function in net/ipv4/ping.c in the Linux kernel before 4.0.3 does not initialize a certain list data structure during an unhash operation, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) by leveraging the ability to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP or IPPROTO_ICMPV6 protocol, and then making a connect system call after a disconnect.

Cross-site scripting (XSS) vulnerability in the 404 error page in Red Hat JBoss Operations Network before 3.3.3 allows remote attackers to inject arbitrary web script or HTML via a crafted URL.

libuser before 0.56.13-8 and 0.60 before 0.60-7, as used in the userhelper program in the usermode package, directly modifies /etc/passwd, which allows local users to cause a denial of service (inconsistent file state) by causing an error during the modification. NOTE: this issue can be combined with CVE-2015-3245 to gain privileges.

Incomplete blacklist vulnerability in the chfn function in libuser before 0.56.13-8 and 0.60 before 0.60-7, as used in the userhelper program in the usermode package, allows local users to cause a denial of service (/etc/passwd corruption) via a newline character in the GECOS field.

The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index.

Pacemaker before 1.1.13 does not properly evaluate added nodes, which allows remote read-only users to gain privileges via an acl command.

The xmlreader in libxml allows remote attackers to cause a denial of service (memory consumption) via crafted XML data, related to an XML Entity Expansion (XEE) attack.

XML external entity (XXE) vulnerability in the dashbuilder import facility (DocumentBuilders in org.jboss.dashboard.export.ImportManagerImpl) in Red Hat JBoss BPM Suite before 6.1.2 allows remote attackers to read arbitrary files, conduct server-side request forgery (SSRF) attacks, and have other unspecified impact via a crafted XML document.

Cross-site scripting (XSS) vulnerability in the manager web interface in mod_cluster before 1.3.2.Alpha1 allows remote attackers to inject arbitrary web script or HTML via a crafted MCMP message.
