It was discovered that KDE KSSL did not properly verify X.509 certificates when the certificate was issued for an IP address. An attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications.
(CVE-2011-1094)
Tim Brown discovered that KDE KHTML did not properly escape URLs from externally generated error pages. An attacker could exploit this to conduct cross-site scripting attacks. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data (such as passwords), within the same domain. (CVE-2011-1168).
