NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2017-0194.NASL description An update is now available for JBoss Core Services on RHEL 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. This release adds the new Apache HTTP Server 2.4.23 packages that are part of the JBoss Core Services offering. This release serves as a replacement for Red Hat JBoss Core Services Pack Apache Server 2.4.6 and includes bug fixes and enhancements. Refer to the Release Notes for information on the most significant bug fixes and enhancements included in this release. Security Fix(es) : * A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library. (CVE-2016-2108) * It was found that the length checks prior to writing to the target buffer for creating a virtual host mapping rule did not take account of the length of the virtual host name, creating the potential for a buffer overflow. (CVE-2016-6808) * It was discovered that OpenSSL did not always use constant time operations when computing Digital Signature Algorithm (DSA) signatures. A local attacker could possibly use this flaw to obtain a private DSA key belonging to another user or service running on the same system. (CVE-2016-2178) * Multiple integer overflow flaws were found in the way OpenSSL performed pointer arithmetic. A remote attacker could possibly use these flaws to cause a TLS/SSL server or client using OpenSSL to crash. (CVE-2016-2177) * It was discovered that specifying configuration with a JVMRoute path longer than 80 characters will cause segmentation fault leading to a server crash. (CVE-2016-4459) * An error was found in protocol parsing logic of mod_cluster load balancer Apache HTTP Server modules. An attacker could use this flaw to cause a Segmentation Fault in the serving httpd process. (CVE-2016-8612) Red Hat would like to thank the OpenSSL project for reporting CVE-2016-2108. The CVE-2016-4459 issue was discovered by Robert Bost (Red Hat).
