REDHAT-BUG-666793: Buffer Overflow
First published: Mon Jan 03 2011(Updated: )
Several stack-based buffer overflows were found in the way gimp processes plug-in configuration files. An attacker could create a a specially-crafted plug-in configuration file and trick the local, unsuspecting user into opening it, which could lead to gimp to crash the plugin or, potentially , arbitrary code execution with the privileges of the user running the executable.
