Security update for the Linux Kernel (important)

The openSUSE 12.3 kernel was updated to fix security issues: This will be the final kernel update for openSUSE 13.2 during its lifetime, which ends January 4th 2015. CVE-2014-9322: A local privilege escalation in the x8664 32bit compatibility signal handling was fixed, which could be used by loca...

kernel: sctp: skb_over_panic when receiving malformed ASCONF chunks

A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol SCTP implementation handled malformed Address Configuration Change Chunks ASCONF. A remote attacker could use either of these flaws to crash the system...

F5 Networks BIG-IP : Linux kernel SCTP vulnerabilities (K15910)

CVE-2014-3673 The SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service system crash via a malformed ASCONF chunk, related to net/sctp/smmakechunk.c and net/sctp/smstatefuns.c. CVE-2014-3687 The sctpassoclookupasconfack function in...

Android system is the presence of the cross-signed certificate vulnerability can lead to system crash-vulnerability warning-the black bar safety net

Overview Trend Micro found the Android system in the presence of a cross-signed certificate handling vulnerabilities. Currently the Android version still does not correctly handle these certificates. When two certificates with a loop certificate chain the certificate of A signature certificate...

Ubuntu 12.04 LTS : linux vulnerabilities (USN-2443-1)

An information leak in the Linux kernel was discovered that could leak the high 16 bits of the kernel stack address on 32-bit Kernel Virtual Machine KVM paravirt guests. A user in the guest OS could exploit this leak to obtain information that could potentially be used to aid in attacking the...

USN-2444-1: Linux kernel (OMAP4) vulnerabilities

Rabin Vincent, Robert Swiecki, Russell King discovered that the ftrace subsystem of the Linux kernel does not properly handle private syscall numbers. A local user could exploit this flaw to cause a denial of service OOPS. CVE-2014-7826 Rabin Vincent, Robert Swiecki, Russell Kinglaw discovered a...

Amazon Linux AMI : kernel (ALAS-2014-455)

The sctpprocessparam function in net/sctp/smmakechunk.c in the SCTP implementation in the Linux kernel before 3.17.4, when ASCONF is used, allows remote attackers to cause a denial of service NULL pointer dereference and system crash via a malformed INIT chunk. CVE-2014-7841 The pivotroot...

kernel: xfs: directory hash ordering denial of service

A denial of service flaw was found in the way the Linux kernel's XFS file system implementation ordered directory hashes under certain conditions. A local attacker could use this flaw to corrupt the file system by creating directories with colliding hash values, potentially resulting in a system...
