Detailsinfo

A vulnerability, which was classified as critical, has been found in KDE. Affected by this issue is an unknown function. The manipulation with an unknown input leads to a heap-based overflow vulnerability. Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). Impacted is confidentiality, integrity, and availability. CVE summarizes:

Heap-based buffer overflow in the encodeURI and decodeURI functions in the kjs JavaScript interpreter engine in KDE 3.2.0 through 3.5.0 allows remote attackers to execute arbitrary code via a crafted, UTF-8 encoded URI.

The bug was discovered 01/20/2006. The weakness was released 01/19/2006 by Maksim Orlovich as confirmed posting (Bugtraq). The advisory is available at securityfocus.com.
