Amazon Linux AMI : kernel (ALAS-2018-1048)

An issue was discovered in the XFS filesystem in fs/xfs/libxfs/xfsattrleaf.c in the Linux kernel. A NULL pointer dereference may occur for a corrupted xfs image after xfsdashrinkinode is called with a NULL bp. This can lead to a system crash and a denial of service.CVE-2018-13094 An issue was...

Amazon Linux 2 : kernel (ALAS-2018-1050)

Linux kernel versions 4.9+ can be forced to make very expensive calls to tcpcollapseofoqueue and tcppruneofoqueue for every incoming packet which can lead to a denial of service. An attacker can induce a denial of service condition by sending specially modified packets within ongoing TCP sessions...

Critical: kernel

Issue Overview: An issue was discovered in the XFS filesystem in fs/xfs/xfsicache.c in the Linux kernel. There is a NULL pointer dereference leading to a system panic in lookupslow on a NULL inode-iops pointer when doing pathwalks on a corrupted xfs image. This occurs because of a lack of proper...

Amazon Linux 2 : kernel (ALAS-2018-1046)

The fs/ext4/inline.c:ext4readinlinedata function in the Linux kernel performs a memcpy with an untrusted length value in certain circumstances involving a crafted filesystem that stores the system.data extended attribute value in a dedicated inode. The unbound copy can cause memory corruption or...

Amazon Linux AMI : ant (ALAS-2018-1047)

It was discovered that Ant's unzip and untar targets permit the extraction of files outside the target directory. A crafted zip or tar file submitted to an Ant build could create or overwrite arbitrary files with the privileges of the user running Ant.CVE-2018-10886 C Tenable Network Security, In...

Amazon Linux 2 : glibc (ALAS-2018-1048)

stdlib/canonicalize.c in the GNU C Library aka glibc or libc6 2.27 and earlier, when processing very long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit architectures, leading to a stack-based buffer overflow and, potentially, arbitrary code...
