Python's elementtree C accelerator failed to initialise Expat's hash salt during initialization. This could make it easy to conduct denial of service attacks against Expat by contructing an XML document that would cause pathological hash collisions in Expat's internal data structures, consuming...

Amazon Linux 2 : krb5 (ALAS-2018-1129)

MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to circumvent a DN containership check by supplying both a 'linkdn' and 'containerdn' database argument, or by supplying a DN string which is a left extension of a container DN stri...

Low: curl

Issue Overview: curl is vulnerable to a buffer overrun in the NTLM authentication code. The internal function Curlntlmcoremknthash multiplies the length of the password by two SUM to figure out how large temporary storage area to allocate from the heap. The length value is then subsequently used ...

Amazon Linux AMI : httpd24 (ALAS-2018-1104)

In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol...
