Local Bufferoverflow in OutlookExpress
Proved Vulnerable: OutlookExpress 4.72

A buffer will overflow if your "Newsgroups:" field contains more than 700
chars. OE will close down with the following "Dr. Watson for Windows NT"
message:
"An application error has occured
and an application error log is being generated
msmn.exe
Exception access violation (0xc00000005), Address: 0x77f64d28"
This will also create a USER.DMP file in your WINNT directory. This file can
be used to extract passwords from, see my previous message to Bugtraq called
"NT stores passwords in plaintext (sp00ky)"
