Hive files are undocumented binary files that Windows uses to store the Windows Registry on disk. Hivex is a library that can read and write to these files. It was found that hivex attempted to read 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. The hivex package has been upgraded to upstream version 1.3.10, which provides a number of bug fixes and enhancements over the previous version. This update also fixes the following bugs: * Due to an error in the hivex_value_data_cell_offset function, the hivex utility could, in some cases, print an "Argument list is too long" message and terminate unexpectedly when processing hive files from the Windows Registry. This update fixes the underlying code and hivex now processes hive files as expected. * A typographical error in the Win::Hivex.3pm manual page has been corrected. Users of hivex are advised to upgrade to these updated packages, which correct these issues and adds these enhancements.
