Description Tomas Hoger 2008-02-27 14:59:13 UTC
From MFSA 2008-12:

Security research firm iDefense reported that researcher regenrecht discovered a
heap-based buffer overflow vulnerability in Mozilla mail code which could
potentially allow an attacker to run arbitrary code. The vulnerability is caused
by allocating a buffer that can be three bytes too small in certain cases when
viewing an email message with an external MIME body.

Workaround:
Users can prevent the vulnerable code from being triggered by setting the
"mailnews.display.disallow_mime_handlers" property to any value greater than or
equal to 3.

Fixed in:
  Thunderbird 2.0.0.12
  SeaMonkey 1.1.8
