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 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...

Amazon Linux 2 : libvirt (ALAS-2018-1049) (Spectre)

An incomplete fix for CVE-2018-5748 that affects QEMU monitor leading to a resource exhaustion but now also triggered via QEMU guest agent.CVE-2018-1064 qemu/qemumonitor.c in libvirt allows attackers to cause a denial of service memory consumption via a large QEMU reply.CVE-2018-5748 An...

Amazon Linux 2 : kernel (ALAS-2018-1044)

A NULL pointer dereference issue was found in the Linux kernel. If the close and fchownat system calls share a socket file descriptor as an argument, then the two calls can race and trigger a NULL pointer dereference leading to a system crash and a denial of service.CVE-2018-12232 C Tenable Netwo...

Amazon Linux 2 : plexus-archiver (ALAS-2018-1043)

A path traversal vulnerability has been discovered in plexus-archiver when extracting a carefully crafted zip file which holds path traversal file names. A remote attacker could use this vulnerability to write files outside the target directory and overwrite existing files with malicious code or...

Amazon Linux 2 : openssh (ALAS-2018-1042)

The processopen function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files.CVE-2017-15906 C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted fro...

Amazon Linux 2 : xdg-user-dirs (ALAS-2018-1030)

It was found that the system umask policy is not being honored when creating XDG user directories /Desktop etc on first login. This could lead to user's files being inadvertently exposed to other local users.CVE-2017-15131 C Tenable Network Security, Inc. The descriptive text and package checks i...

Amazon Linux 2 : procps-ng (ALAS-2018-1031)

Multiple integer overflows leading to heap corruption flaws were discovered in file2strvec. These vulnerabilities can lead to privilege escalation for a local attacker who can create entries in procfs by starting processes, which will lead to crashes or arbitrary code execution in proc utilities...

Amazon Linux 2 : 389-ds-base (ALAS-2018-1036)

It was found that 389-ds-base did not properly handle long search filters with characters needing escapes, possibly leading to buffer overflows. A remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially crafted LDAP request, thus resulting in denial...

Amazon Linux 2 : qemu-kvm (ALAS-2018-1034) (Spectre)

An out-of-bounds read access issue was found in the VGA display emulator built into the Quick emulator QEMU. It could occur while reading VGA memory to update graphics display. A privileged user/process inside guest could use this flaw to crash the QEMU process on the host resulting in denial of...
