Mozilla Thunderbird contains a heap-based buffer overflow which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Mozilla Thunderbird is an open source, cross-platform email and news client. Thunderbird uses Multipurpose Internet Message Extensions (MIME) which extends support in Thunderbird for multi-part message bodies, non-text attachments, and non-ASCII character sets. A vulnerability exists in the way Mozilla Thunderbird parses external-body MIME type in an electronic mail which may result in a heap-based buffer overflow. According to Mozilla Foundation Security Advisory 2008-12:
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.
A remote, unauthenticated attacker may be able to execute arbitrary code on a system running a vulnerable version of Mozilla Thunderbird.
