The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * It was found that the Linux kernel"s IPv6 implementation mishandled socket options. A local attacker could abuse concurrent access to the socket options to escalate their privileges, or cause a denial of service via a crafted sendmsg system call. * Several Moderate and Low impact security issues ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/environ. An unprivileged, local user could potentially use this flaw to esc ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * A use-after-free vulnerability was found in the kernels socket recvmmsg subsystem. This may allows remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg function. Bug Fix: * Previously, gu ...

This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg function. * An out-of-bounds heap me ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. These updated kernel packages include several security issues and numerous bug fixes, some of which you can see below. Space precludes documenting all of these bug fixes in this advisory. To see the complete list of bug fixes, users are directed to the related Knowledge Article: https://access.redhat.com/articles ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946. * A flaw ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * It was found that the packet_set_ring function of the Linux kernel"s networking implementation did not properly validate certain block-size data. A local attacker with CAP_NET_RAW capability could use this flaw to trigger a buffer overflow, resulting in the crash of the system. Due to the nature o ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * A flaw was found in the way Linux kernel allocates heap memory to build the scattergather list from a fragment list in the socket buffer. The heap overflow occurred if "MAX_SKB_FRAGS + 1" parameter and "NETIF_F_FRAGLIST" feature were used together. A remote user or process could use this flaw to p ...

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * An use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system. * A flaw was found that can be triggered in keyring_search_iterator in keyring.c if type-m ...

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. The php54 packages provide a recent stable release of PHP with the PEAR 1.9.4, APC 3.1.15, and memcache 3.0.8 PECL extensions, and a number of additional utilities. The php54 packages have been upgraded to upstream version 5.4.40, which provides a number of bug fixes over the version shipped in Red Hat Software C ...
