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 reporting emulation failures to user space could lead to either a local or a L2->L1 denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. Please note that on certain systems, HPET is mappe ...

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-g ...

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 ...

PCRE is a Perl-compatible regular expression library. Security Fix: * Multiple flaws were found in the way PCRE handled malformed regular expressions. An attacker able to make an application using PCRE process a specially crafted regular expression could use these flaws to cause the application to crash or, possibly, execute arbitrary code

The libxml2 library is a development toolbox providing the implementation of various XML standards. Security Fix: A heap-based buffer overflow flaw was found in the way libxml2 parsed certain crafted XML input. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or execute arbitrary code with ...
