KDE : Security Vulnerabilities, CVEs, Published In July 2004

Konqueror 3.1.3, 3.2.2, and possibly other versions does not properly prevent a frame in one domain from injecting content into a frame that belongs to another domain, which facilitates web site spoofing and other attacks, aka the frame injection vulnerability.

The URI handlers in Konqueror for KDE 3.2.2 and earlier do not properly filter "-" characters that begin a hostname in a (1) telnet, (2) rlogin, (3) ssh, or (4) mailto URI, which allows remote attackers to manipulate the options that are passed to the associated programs, possibly to read arbitrary files or execute arbitrary code.
