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.
Konqueror in KDE 3.1.3 and earlier (kdelibs) allows remote attackers to bypass intended cookie access restrictions on a web application via "%2e%2e" (encoded dot dot) directory traversal sequences in a URL, which causes Konqueror to send the cookie outside the specified URL subsets, e.g. to a vulnerable application that runs on the same server as the target application.
Buffer overflow in the VCF file information reader for KDE Personal Information Management (kdepim) suite in KDE 3.1.0 through 3.1.4 allows attackers to execute arbitrary code via a VCF file.
Konqueror in KDE 3.0.3 allows remote attackers to cause a denial of service (core dump) via a web page that begins with a "xFFxFE" byte sequence and a large number of CRLF sequences, as demonstrated using freeze.htm.
KDM in KDE 3.1.3 and earlier does not verify whether the pam_setcred function call succeeds, which may allow attackers to gain root privileges by triggering error conditions within PAM modules, as demonstrated in certain configurations of the MIT pam_krb5 module.
KDM in KDE 3.1.3 and earlier uses a weak session cookie generation algorithm that does not provide 128 bits of entropy, which allows attackers to guess session cookies via brute force methods and gain access to the user session.
KDE Konqueror for KDE 3.1.2 and earlier does not remove authentication credentials from URLs of the "user:password@host" form in the HTTP-Referer header, which could allow remote web sites to steal the credentials for pages that link to the sites.
Konqueror Embedded and KDE 2.2.2 and earlier does not validate the Common Name (CN) field for X.509 Certificates, which could allow remote attackers to spoof certificates via a man-in-the-middle attack.
Safari 1.0 Beta 2 (v73) and earlier does not validate the Common Name (CN) field for X.509 Certificates, which could allow remote attackers to spoof certificates.
The GnuPG plugin in kopete before 0.6.2 does not properly cleanse the command line when executing gpg, which allows remote attackers to execute arbitrary commands.
