Amazon Linux AMI : bind (ALAS-2015-573)

As reported upstream, an error in the handling of TKEY queries can be exploited by an attacker for use as a denial-of-service vector, as a constructed packet can use the defect to trigger a REQUIRE assertion failure, causing BIND to exit. C Tenable Network Security, Inc. The descriptive text and...

Amazon Linux AMI : gnupg2 (ALAS-2015-574)

It was reported that gnupg2 keyring DB code did not reject packets which don't belong into a keyring, which may lead to invalid read of sizeof int. C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted from Amazon Linux AMI Security Advisory...

Amazon Linux AMI : usermode / libuser (ALAS-2015-572)

It was found that libuser, as used in the chfn userhelper functionality, does not properly filter out newline characters, which allows an authenticated local attacker to corrupt the /etc/passwd file and cause denial-of-service against the system. CVE-2015-3245 A flaw was found in the way the...
