Detail
Problem Description: An updated haproxy package that fixes one security issue is now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Load Balancer (v. 6) - i386, x86_64 3. Description: HAProxy provides high availability, load balancing, and proxying for TCP and HTTP-based applications. A flaw was found in the way HAProxy handled requests when the proxy's configuration ("/etc/haproxy/haproxy.cfg") had certain rules that use the hdr_ip criterion. A remote attacker could use this flaw to crash HAProxy instances that use the affected configuration. (CVE-2013-2175) Red Hat would like to thank HAProxy upstream for reporting this issue. Upstream acknowledges David Torgerson as the original reporter. HAProxy is released as a Technology Preview in Red Hat Enterprise Linux 6. More information about Red Hat Technology Previews is available at https://access.redhat.com/support/offerings/techpreview/ All users of haproxy are advised to upgrade to this updated package, which contains a backported patch to correct this issue. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 5. Bugs fixed (http://bugzilla.redhat.com/): 974259 - CVE-2013-2175 haproxy: http_get_hdr()/get_ip_from_hdr2() MAX_HDR_HISTORY handling denial of service |
