Amazon Linux AMI : ntp (ALAS-2018-1083)

ntpd in ntp 4.2.x before 4.2.8p7 allows authenticated users that know the private symmetric key to create arbitrarily-many ephemeral associations in order to win the clock selection of ntpd and modify a victim's clock via a Sybil attack. This issue exists because of an incomplete fix for...

Amazon Linux 2 : qemu-kvm (ALAS-2018-1073)

A heap buffer overflow issue was found in the way SLiRP networking back-end in QEMU processes fragmented packets. It could occur while reassembling the fragmented datagrams of an incoming packet. A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS...

Amazon Linux 2 : mutt (ALAS-2018-1077)

An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. pop.c does not forbid characters that may have unsafe interaction with message-cache pathnames, as demonstrated by a '/' character.CVE-2018-14362 An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-1...

Amazon Linux 2 : policycoreutils (ALAS-2018-1076)

Context relabeling of filesystems is vulnerable to symbolic link attack, allowing a local, unprivileged malicious entity to change the SELinux context of an arbitrary file to a context with few restrictions. This only happens when the relabeling process is done, usually when taking SELinux state...

Amazon Linux 2 : mariadb (ALAS-2018-1078)

Vulnerability in the MySQL Server component of Oracle MySQL subcomponent: Server: Optimizer. Supported versions that are affected are 5.5.57 and earlier. Easily exploitable vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Server. Successf...
