Status Candidate

Mandriva Linux Security Advisory 2013-274
Posted Nov 21, 2013
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2013-274 - A Heap-based buffer overflow was found in the way libjpeg-turbo decompressed certain corrupt JPEG images in which the component count was erroneously set to a large value. An attacker could create a specially-crafted JPEG image that, when opened, could cause an application using libpng to crash or, possibly, execute arbitrary code with the privileges of the user running the application. libjpeg 6b and libjpeg-turbo will use uninitialized memory when decoding images with missing SOS data for the luminance component in presence of valid chroma data. libjpeg-turbo will use uninitialized memory when handling Huffman tables.
