Mandriva Linux Security Advisory 2013-110 - An out-of heap-based buffer bounds read and write flaw, leading to invalid free, was found in the way a tile coder / decoder implementation of OpenJPEG, an open-source JPEG 2000 codec written in C language, performed releasing of previously allocated memory for the TCD encoder handle by processing certain Gray16 TIFF images. A remote attacker could provide a specially-crafted TIFF image file, which once converted into the JPEG 2000 file format with an application linked against OpenJPEG , would lead to that application crash, or, potentially arbitrary code execution with the privileges of the user running the application. An input validation flaw, leading to a heap-based buffer overflow, was found in the way OpenJPEG handled the tile number and size in an image tile header. A remote attacker could provide a specially-crafted image file that, when decoded using an application linked against OpenJPEG, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. It was found that OpenJPEG failed to sanity-check an image header field before using it. A remote attacker could provide a specially-crafted image file that could cause an application linked against OpenJPEG to crash or, possibly, execute arbitrary code.
