Detailsinfo

A vulnerability, which was classified as problematic, was found in KMail (Mail Client Software) (the affected version is unknown). This affects an unknown code of the component Plaintext Viewer. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on integrity. The summary by CVE is:

Through a malicious URL that contained a quote character it was possible to inject HTML code in KMail's plaintext viewer. Due to the parser used on the URL it was not possible to include the equal sign (=) or a space into the injected HTML, which greatly reduces the available HTML functionality. Although it is possible to include an HTML comment indicator to hide content.

The bug was discovered 12/23/2016. The weakness was published 12/23/2016 by Albert Astals Cid (Website). The advisory is shared at lists.opensuse.org.
