Description Jan Lieskovsky 2012-06-05 12:52:18 UTC

A security flaw was found in the way malloc() and calloc() routines implementation in Hoard, a fast, scalable, and memory-efficient allocator, performed validation of their arguments for overflows. If an application using Hoard memory allocator was missing application-level malloc() and calloc() routines arguments validity checks, a remote attacker could provide a specially-crafted application-specific input file, leading to that application crash or, potentially, arbitrary code execution with the privileges of the user running the application.

Based on [1], this issue affects the v3.8 versions (thus also those, which are currently being shipped in Fedora release of 15, 16, and 17) of Hoard.

Please schedule an update for these hoard versions, once there is final upstream patch available.
