Hivex is a library that can read and write Hive files, undocumented binary files that Windows uses to store the Windows Registry on disk. It was found that hivex attempted to read, and possibly write, beyond its allocated buffer when reading a hive file with a very small size or with a truncated or improperly formatted content. An attacker able to supply a specially crafted hive file to an application using the hivex library could possibly use this flaw to execute arbitrary code with the privileges of the user running that application. Red Hat would like to thank Mahmoud Al-Qudsi of NeoSmart Technologies for reporting this issue. This update also fixes the following bug: * The hivex man page previously contained a typographical error. This update fixes the typo. All hivex users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
