[GLSA-200612-05] KOffice shared libraries: Heap corruption |
||
KOffice shared libraries: Heap corruption Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200612-05 (KOffice shared libraries: Heap corruption) Kees Cook of Ubuntu discovered that 'KLaola::readBigBlockDepot()' in klaola.cc fills 'num_of_bbd_blocks' while reading a .ppt (PowerPoint) file without proper sanitizing, resulting in an integer overflow subsequently overwriting the heap with parts of the file being read. Impact By enticing a user to open a specially crafted PowerPoint file, an attacker could crash the application and possibly execute arbitrary code with the rights of the user running KOffice. Workaround There is no known workaround at this time.
