Multiple remote overflows exist in AbiWord. The 'ParseLevelText()', 'getCharsInsideBrace()', 'HandleLists()', and 'HandleAbiLists()' functions in 'ie_imp_RTF.cpp' fail to perform proper bounds checking resulting in multiple stack-based buffer overflows. With a specially crafted RTF file, a remote attacker can cause arbitrary code execution resulting in a loss of integrity.
