The InfiniBand (IB) implementation in the Linux kernel package does not properly restrict use of User Verbs for registration of memory regions, which allows local users to access arbitrary physical memory locations, and consequently cause a denial of service (system crash) or gain privileges, by leveraging permissions on a uverbs device under /dev/infiniband/.

The kernel package contains the Linux kernel , the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.

Updated php packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having critical security impact. A Common Vulnerability Scoring System base score, which gives a detailed severity rating, is available from the CVE link in the References section. Description PHP is an HTML-embedded scripting languag ...

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. A flaw was found in the way the php-cgi executable processed command line arguments when running in CGI mode. A remote attacker could send a specially-crafted request to a PHP script that would result in the query string being parsed by php-cgi as command line options and arguments. This could lead to the disclos ...

* A flaw was found in the way the Linux kernel"s SCTP implementation handled malformed or duplicate Address Configuration Change Chunks . A remote attacker could use either of these flaws to crash the system. * A flaw was found in the way the Linux kernel"s SCTP implementation handled the association"s output queue. A remote attacker could send specially crafted packets that would cause the syste ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. * It was found that the Linux kernel"s Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges ...
