Detail
| Problem Description: Updated libunwind packages that fix one security issue are now available for Red Hat Enterprise Linux OpenStack Platform 5.0 for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Low 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 OpenStack Platform 5.0 for RHEL 6 - x86_64 3. Description: Libunwind provides a C ABI to determine the call-chain of a program. An off-by-one array indexing error was found in the libunwind API, which could cause an error when reading untrusted binaries or dwarf debug info data. Red Hat products do not call the API in this way; and it is unlikely that any exploitable attack vector exists in current builds or supported usage. (CVE-2015-3239) This issue was discovered by Paolo Bonzini of Red Hat. All users of libunwind are advised to upgrade to these updated packages, which contain 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.
