CVE-2004-0632

Status: ModifiedHigh (7.5)—

Adobe Reader 6.0 does not properly handle null characters when splitting a filename path into components, which allows remote attackers to execute arbitrary code via a file with a long extension that is not normally handled by Reader, triggering a buffer overflow.

CVSS
