Stack-based buffer overflow in the _chm_find_in_PMGL function in chm_lib.c for chmlib before 0.36, as used in products such as KchmViewer, allows user-assisted attackers to execute arbitrary code via a CHM file containing a long element, a different vulnerability than CVE-2005-3318.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
