Rekonq 0.7.0 and earlier does not use a certain font when rendering certificate fields in a security dialog, which allows remote attackers to spoof the common name (CN) of a certificate via rich text.

The remote host is affected by the vulnerability described in GLSA-201412-09 (Multiple packages, Multiple vulnerabilities fixed in 2011)

    There are no known workarounds at this time.

KDE Security Advisory reports :

The default rendering type for a QLabel is QLabel::AutoText, which uses heuristics to determine whether to render the given content as plain text or rich text. KSSL and Rekonq did not properly force its QLabels to use QLabel::PlainText. As a result, if given a certificate containing rich text in its fields, they would render the rich text.
Specifically, a certificate containing a common name (CN) that has a table element will cause the second line of the table to be displayed.
This can allow spoofing of the certificate's common name.
