Description

KOffice is prone to an overflow condition. The read() function of filters/words/msword-odf/wv2/src/styles.cpp fails to properly sanitize user-supplied input resulting in a heap-based buffer overflow. With a specially crafted ODF file, a context-dependent attacker can potentially execute arbitrary code.
