NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2014-1292.NASL description An updated haproxy package that fixes one security issue is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. HAProxy provides high availability, load balancing, and proxying for TCP and HTTP-based applications. A buffer overflow flaw was discovered in the way HAProxy handled, under very specific conditions, data uploaded from a client. A remote attacker could possibly use this flaw to crash HAProxy.
